Entry is amazing Amit sir💐💐👌👌. But we miss a man with white board and one black glove in pace batch.😢☺️☺️🤔🤗🤗

PW changed my life. Thank you PW team. Hope I will contribute as an Alumni in future!

sir ne jo trick and process bataye hain wo bahut hi zyada helpful hain physicswallah sir ko aur amit sir ko itna quality content free mein dene k liye jitna thanks kahoon utna kam hai ..........

Thank you.... thank you...So much sir!!!!!! My all doubts about stoichiometry has been crystal clear. I'm so glad I found u...And I would also like to thank alakh sir😭🙏to bring such a perfectionist

if anyone is here for only to understand LIMITING REAGENT it starts in 58:03

Golden Tip for those guys who are not getting mole-mole analysis properly- This is a very simple concept but it is looking tough due to that hypothetical reaction, sir is explaining this from very basics that's why it seems to be boring. If u watch that particular part 2-3 times then you'll surely get it👍

Excellent teaching and thanks to alakh Pandey sir for providing for free for us

I think in the formula of moles in terms of volumes the standard volume should be 22.4 litres instead of 22.7 litres.

Mole mole analysis at the time from 40 to 48 min is so confusing 😖😖 After sir's so much effort also I am so confused at that time

I always thought that begin a musician actor or an astronaut would be that coolest to do it. But I realize that none of that would be possible there weren't teacher like you. 🙏🙏💪💪

Sir hypothetical jo bhi ho uska ek example deke samjha dijiyega kio k kuch students ko kam samjh ata hai jaise mai hu 😣 jaise xyz, abcd ese samjhane se dimag mai nai baithta 🥺🥺

Amazing .....sir you are genius. I faced lot of problems in solving stoichiometry and LR but your lecture made it soo easy. Thanks a lot sir for this knowledgeable lecture. Stay blessed sir.

Don't drink WATER while watching this CHEMISTRY class because CHEMISTRY says that WATER decreases CONCENTRATION !

My concepts are getting really clear by pace batch not just chem but every subject... loving batch

I need to say this, You are a genius........The mass-mass analysis was basic but I wasn't getting it but your formula....DAMN!

1:02:09 in case is volume, the formula would be given volume (at STP) / 22.4L Instead of 22.7 Just that's what I want to correct! Apart your explaination is absolute amazing! Thank you so much

Thank you Sir for an amazing lecture, I was always confused in this topic.

Can we take volume at stp 22.4 ?

What is difference between 22.4 and 22.7 at STP condition ? 30:01

Every thing is temporary but the saying " padayi krtay rahay oll the very best 'is constant.... ♥️🙂💫

Thnx a lot outstanding explanation I watched many videos of the explanation of stoichiometry but I can't understand But when I watch your video it boost my concept😊

Volume of any gast at stp means (pressure- 1atm and temp-0 degree) Is 22.4 dm³ not 22.7

sir a humble request hai sir please example se samjaya kareye hypothetical equation se samajne me dikkat hota hai plzzz sir except that i love your teaching sir you are the best

Sir, Please start regular exams(or unit tests) also for Class 11(doesn't matter if we have to pay for that) Please Sir Please 🙏🙏🙏

Sir , 30:00 pe 22.4 L at STP hoga na

Guys see I don’t want ki kissi ka bura ho but plzzz hear this out this video is really confusing and it made me think that this topic is so difficult but instead of watching this video go to the old video of aalakh sir where he is teaching the same topic omg he has explained so easily this sir is just making things more and more difficult and if u don’t believe me after watching the old video come back here and just fast forward to the sum part u will be able to solve each and every sum very easily plz I highly recommend don’t waste ur time here

Minimum 10 videos dekha hu alag alag ytber ke pr sir ap se hi samjha your ar great ❤

Someone*: "Preparing for JEE is boring" Le me*: ""Watch Rohit sir's Thumbnail ,Aman sir's and Amit sir's entry""😁 ( Samajdar ko ishare kaffi he🤘 )

1:09:34 the remaining or left out reactant is called the excess reactant

0:12 Physics wallah is litterraly now making a surakh in Aakash. If u understand this u r a legend😂😂😂

Sir please example k sath samjhaye mole mole analysis last 20 min mai bhot confuse hogye thi kuch smaj nai aya

Mole Mole analysis is so confusing

I'm very much impressed by ur efforts sir.... srsly we need more selfless people like you

Aaj ka topic thoda boring hai..... 🙄 But sir apna 💯%effort lga rhe hai👍👍👍

I think, ..... Mole _mole analysis is very important.. Three formulas is important which helped in Short time 1) mole=mass/molar mass 2)mole =volume (at STP) /22.414dm³. 3) mole=given particles/Nà

At 7:00, Sir: sabse pehla kaam kya hai? Me: ek sundar diagram!😂😂 Then I realised that it's chemistry lecture!!!!!!!!!😂😂🤣🤣😆😆

Sir please help me ,(Mass- mass analisis me reactant ek tha to 2 product se reatio kiye yadi LHS me bhi 2 reactans hoti to kaise ratio lete?) sir.

Pace batch is tooooooo helpful 🖒🖒motivating ..non procastinational ..with best teachers ever

SIR'S FAVORITE DIALOGUE "MAYABI DUNIYA"" KE ANDAR CHALTE HE 👦

I watch it with 1.5x and still have no problem 👍👍👍👍👍👍👍👍👍👍👍 And i managed the time 💥💥💥💥💥

But molar volume of any gas at stp is 22.4L,am i right?

What a intro gajab ki entry jaisa chapter uske opposite padhane ka style kya style h padhane ka seriously Bohot hard bohot hard 😂😂 Really great ❤️❤️❤️

Sir is taking volume at stp as modern value but it still used as 22.4 l in jee

I cleared all concepts by watching this video....!!!! Thanks 🙏

Sir i have a doubt What is non stoichiometric compounds and why they do not follow law of multiple proportion

Sir hypothetical equation ki jagah real equation lijiye

Me- struggling to understand stoichiometry in online classes Amit Sir-Hold my stylus

Can anyone tell me, Are these lectures enough for jee without any coaching?

One like for sir's efforts...

apne basic se start kiya or saare concept clear kr diya. thank you sir.

Sir Please Start A 24 Month Batch For 11th + Neet/Jee Foundation On Your PW Aap Sir Sir Mai Aapke Bharose Hu !! *Must Needed* *Must Needed*

Ans. 2.18 : 1.29 : 1.39 In whole number Can be written as 2:1:1

Best Teacher of chemistry in india Amit sir

THANK YOU SIR I WAS ABLE TO SOLVE THE MOST DIFFICULT QUESTIONS AFTER WATCHING THIS VIDEO

Such a wonderful explanation sir... Very helpful, keep uploading. Thank you...

What a great entry by Amit sir. Amit sir u r a great teacher of chemistry.

Sir u r great Choti choti baat bhi boht acchi tarah se smjhate ho aap Tq alakh sir and full pw team For giving us such great faculties Kya alakh sir k b koi hater ho skta h

Physics wallah is just amazing and cleared my every doubt😌😌

Alakh Sir Great Sir👍 👇

We Are Thankful Of You sir😍😍😍😍

Didn't understood when watched first time. But now learnt by heart when watched 6-7 times. Please do the same.

Sir pls also bring jee advanced level mock test or test series and dpps for us its my humble request to you sir... ❤for this you can also charge us.. Sir plz provide bcz by giving regular test we got to know where we stand in 1000 of aspirants...

29.58 no of moles=v at stp/22.4litres if u want check in google

Sir...Mole-Mole Analysis pe ek question last me dete toh concept jyada clear hota...i m still in confusion state about mole mole analysis.

Mathematics sir & chemistry sir has an amazing entry. Like bollywood actor as singham. 🔥🔥🔥❤️❤️❤️

World's best educational channel in the world ❤❤ love this channel

34:44 sir STP ki condition n=v(c) 22.4

Sir you are really awesome teacher 👍👍👍👍👍👍 We all wants to study with you all time in chemistry 👍👍👍👍👍👍👍👍

Thanku so much sir I was always confused in this topic now I understand this lecture clearly

Every lecture of Amit sir on a particular topic is sufficient to get the basic to advanced knowledge of that topic.🙌

Itne baar stoichiometry samajhne ki koshish ki pr samajh nhi aai but aapka lecture ek baar dekhne me sare concept Cristal clear ho gye thankyou sir😍

Woww....thank u so much sir..it's really helping me a lot✌❤...god bless you🙏

Sir vo to 22.4 L hota tha na STP pe aapne 22.7L kyu Kara please yeh confusion dur kar do

I am become more energetic when i see the entry😂 and thank you so much sir🙂

Sir plz give example of mole -mole analysis

Hello guys! I'm from 2075. Most of PW videos have 200 M+ views now; he has a subscriber count of 30 M and his app has 30M+ downloads. He's brand is competing with all Kota factories combined. And beside teaching students, he has started to provide jobs to his company.

40:39 sir oxygen ka vol 102.15 aa rha h Numerator(3×3×22.7=25026.75) and denominator(122.5×2=245 )aa rha h and dono ko divide kar ke 102.15 aa rha h

Who can't understand mole - mole analysis ☺️🖤

why do we consider 22.7l instead of 22.4l in mass volume analysis?

Nice lecture ✌✌ Thank you sir.... 🙏🙏 ...😇😇

should that not be n×22.4 not 22.7????

Got the video first and notification later 😂😂...thnx for you hard work for all of us ❤️❤️

40:00 ky ham oxygen ka volume n=v/22.4 se nikal skte h

Thank you so much sir for making this topic crystal clear to us 🙏🏻🙏🏻

How we find out the mass of kcl if the mass of kclo3 is given???

Sir can I solve neet level books for jee mains(Not Advance) Chemistry

45:14 par sir ye x times hua aur agar y times hua ka kya matlab hai?🤔

Sir eagerly waiting for Atomic structure video

Welcome to the *What should I comment to get more likes* club.

Amit sir teaches really well☺️

I am not criticizing the study techniques and the good work that they are doing. At some points sir has written some wrong data Volume of one mole gas at STP 22.4L not 22.7 L It is the mistake at approx 32 minutes

Sir it better to take examples to explain the mole-mole analysis and limiting reagent, with variables it,s confusing.

why 100 gm reactant and 56 and 44 are products in mass mass equation

Thanku sir for such a nice ND conceptual lecture 😍😍

Sir explanation is best but try to explain mole- mole analysis by real example not throughout with variables.❤❤

Physical chemistry is awesome 💜

Sir actually volume at stp is :22.4 litres

Sir plz taught us mole mole analysis by giving a suitable example

Wow sir, u are just great, out of this world, outstanding, amazing, awesome, excellent, brilliant, magnificent, ek dum majjedaar.
