In this video, you'll learn how to find the actual yield, theoretical yield, and percent yield by working through an example together.
It's really just a matter of knowing the equation: % yield = actual yield / theoretical yield x 100%. Actual yield is the amount of products that is actually produced in the experiment. Theoretical yield is the amount of products that can be produced if the experiment went 100% according the plan without error.
To find theoretical yield, use stoichiometry to convert the given reactants into the grams of the desired product.
By the end of this video, you'll know exactly how to find actual yield, theoretical yield, and percent yield.

well you don't need the actual yield to find the theoretical yield

@ProductDesigner1989 5 лет назад

Hi, why is that your theoretical yeild is 17.4g? Where did you take it?

@azca. 3 года назад

Remove all the slashes and you get: 9.87(60.056/17*2)

@Con-jq9ly 2 года назад

This was really helpful only issue i noticed being that multiplying by 100% is the same as multiplying by one (% = /100 => 100% = 100/100 = 1) so it is time 100 not times 100% but again aside from that it is extremely helpful

@geraldramos1689 6 лет назад

why did you used 75% instead of 79% in calculating actual yield?

@Ebrech 5 лет назад

It's a typo, should have been 79%

@soueivs5germscodm268 2 года назад

Why 17.4 how u calculate it

@froyvincentcorbita8651 3 года назад

Is it possible for the actual yield to be more than the theoretical yield?

Ok, but what if the problem doesn’t give you an actual yield or the percentage yield??? I have no clue how to find the actual yield all on its own...

@euph0rya672 4 года назад

Its impossible to find actual yield if % yield isn’t given

@wizzie9231 4 года назад

I'm no scientist but that does not sound humanly possible.

@SummerDiablo 6 месяцев назад

I have a question they didn't give me the percent nor actual yeild of the product just the moles of the reactants and I have to find percentage yeild HOWWWWWW

@noahleider5884 Год назад

the actual yield was given. I was hoping you would show us how to find the actual yield.

@srglmr 5 лет назад

thats not finding ACTUAL YIELD its giving in your example how to get the actual yield from the side reaction

@euph0rya672 4 года назад

I cant speak from experience the only way to find actual yield is if the % yield is given then u need to find theoretical yield then equate it and cross multiply

@khatger 5 лет назад

i got the percentage yield one but the actual yield one was not helpful but thanks alot bro!

@SaaraEPShaundalwa-hf7ig Год назад

How did you get 17.4 theoretical yeild??? I’m so confused dude

@ahmadmikhail9187 3 года назад

from the equation he made.....is ur calc giving other answers other than 7.39...?

@casinovathedon8924 3 года назад

Ill explain it with an easier method. . . First work out the moles of Ammonia which is n=M/Mr =9.87/17=0.581 to 3 significant figures From the balanced equation, you can see that 2 moles of Ammonia react to give 1 mole of Urea So the mole to mole ratio is 2:1 so the moles of Urea is 0.2905 Now you can work out the Maximum theoretical mass of Urea with teh formula Mass=Mr x n(moles) The relative molecular mass of Urea is 60 and the moles are 0.2905 as worked out earlier. 60 multiplied by 0.2905=17.43g % Yield = Actual mass of product (13.74)/maximum theoretical mass(17.43)X100 = 78.8% Hope this helps

@FreshSongs-AND-SOON-Politics 2 года назад

The semantics of this subject as it is typically taught is all over the place. It bothers me that we call this a gram to gram conversion. It makes it seem like we are measuring the same chemicals when we say conversation, or like we are switching units. The semantics of it all had me confused for years. We are dealing with gram to gram ratios. And yes, while something is being converted, it is not grams being converted. So the name, "gram to gram conversion" is unessessarily and frustratingly distracting from the overall goal.
