Chemistry | Stoichiometry | How to calculate percentage purity 

Ever since I started taking this lessons my marks have improved Thank you uncle M for Making me a physician ❤😊

Thank you so much for the lesson. I've been battling with this since grade 10 but now I actually understand it. Thanks for adding 8 marks to my chemistry paper😭❤

I never understood when my chemistry teacher taught me.However, i understand with you. Thanx 🎉😊

Can you please do more videos on chemistry (percentage yield , purity , empirical formulae etc)

Wola! Wola! Thank you for the great service, your work is really appreciated.👏

This is a very helpful video.Thankyou so much

On 8:35 when you said “This is the total mass.that mass that they gave me, that’s a total Mass.” & I nodded yhoo!!yes it is but also realized my head is on Mess Not mass.That’s when i knew i needed to take a break😂. Thank you for your efforts Sir🙏🏾

Thank you ❤️ may God continue to bless you with more clients🙏🥺♥️

Thank you so much Mr for the good lessons,you are the best physical science and mathematics teacher i've ever come across..May God bless you 😭❤🙏

Uncle I have a question to why didnt you multiply the molar mass of aluminum by2 (n=m/M , 0.2=m/2(27) because aluminum is like this 2Al ?

Thank you very much sir God bless you

This guy is amazing. Thank you so much

So great you just saved I've been looking for this video the whole day ☺️

Thank you sir , very helpful

Please show us the other method. Thank you for the video!

You are really one of the best 🔥💯🏆your lesson was well delivered

Sir siyabonga 🎉🎉🎉

You are the best 🙏

Thank you!

good day sir when you were calculating the molar mass for aluminium aren't we supposed to also include the coeficient in the calculations?

Sir for 10:08 why did we not use n=m÷M for the mole because we had 8g of aluminum.... Because if we said n=m÷M it was going to be n=8÷27(aluminum) and our n was still going to be 0.296=0.3

Thanking

Thanks

Thank you so much sir

❤

sir can you please do grade 10. ❤

Sir can you please do a video on acids and base that contains three reactions and how to reverse them

Noiceee!!!!!

Hi sir can yoj please do a video on electrodynamics

Sorry sir you did a mistake on Allumini. ...You.suppose to multiply by to. The mollar mass

Hi sir ,so the mass they give us , we should not use it ?

How would u calculate the impure mass?? If u were given the pure mass.

Hi so than sir when do we actually use the coefficients of the equation in calculations?

Isn't %purity = mass concentration of *impure* Al/mass concentration of pure Al, not the other way around?

How do i calculate if given percentage

Hello sir,when we calculate the molar mass we don't consider the ratios?

An hour before my final chemistry exam😂😂

We no longer need the organic chemistry tutor 👍

Mlungisi my dhiye!!!! I’m going to buy you a new car uyava?🤭🤭🤭

what the sigma

Thak you Bu Im suffer for whatapp number

Thank you so much Sir
