Actual yield

[Monica Soliman 3F]

Is the yield always given or do we have to calculate for it at some point? Thank you.

[Wasila Sun 2I]

I've seen some hypothetical questions where the percent yield is 100% so you are calculating the actual and theoretical yield. But, I haven't seen any questions where you have to calculate the actual yield if the percent yield isn't 100%.

[Colin Squire 3B]

I'm just pulling from my past knowledge of AP chem. The theoretical yield will always be 100%. When we were asked to solve for the actual yield it was in a lab setting where we physically had to measure it out, otherwise I'd just say it would have to be given information for like a homework assignment.

[Lucy Wang 2J]

You should be able to calculate the theoretical yield. As for the actual yield, I think this is usually given to you or maybe as a percentage of the theoretical yield, so that you would be able to solve for the actual yield.

[Lorraine Medina 3E]

Hi Monica!
Considering we are not in the actual lab, I'm assuming actual yield will be given to us. Other than that, I think we will usually be asked to calculate theoretical yield and/or precent yield.

[Shalyn Kelly 3H]

Hi! I believe for written problems it will typically be given to you unless you are to find it. In which case you should be able to find/be given the theoretical and percent yields. I think you multiply the theoretical and percentage yield to get the actual yield.
Think of it with the formula: (actual yield)/(theoretical yield) x 100 = (% yield)
But, for now, I think we will be calculating the theoretical/% yield.

[Lizbeth Garcia 1F]

I would assume since we cannot get it in a lab then most likely they will give it to us. Unless, of course, they give the other components with which can calculate it off of.

[Jerry_T]

If the question asks for percent yield, then actual yield should be given. I hope this answers your question!

[David Liu 1E]

Actual yield should be able to be calculated given certain information from the problem, though the questions that we've done so far mostly have them given. I think that in the future we might get questions that ask us to calculate both given idealized information but I think all the questions this week have given them when necessary iirc.

[Joanna Huang]

The theoretical yield should always be 100%. As for the actual yield, if the number is not given, then the problem will always provide a method to solve for the actual yield. For example, the problem should usually tell you what the molar mass of the final product is, and using that number and the theoretical yield that you calculated in the previous part of the question, you should be able to calculate the actual yield.

[Emilie_Paltrinieri_1K]

You can calculate the theoretical yield in problems as it is the value with the optimal efficiency of the experiment. But, in some cases, the actual yield doesn't match the theoretical yield as, for example, some solution can stick to the beaker.

[Lea Chamoun 2J]

The theoretical yield is the amount of product you calculate in the problem given the amount of reactants given, and it assumes that the reaction worked perfectly, which does not happen in a real experiment. The actual yield would be given in the problem, and you divide the actual yield by the theoretical yield calculated to find the percent yield.

[Sarina Mak 1B]

I think the actual yield should be given, unless we were in a lab or something, but the theoretical yield should be calculated.

[Sydney Jensen 3L]

The actual yield will be provided, even if it not explicitly spelled out, will be in the problem, and then you just calculate the theoretical yield, and then divide actual by theoretical yield, and then multiply by 100 to get the percent yield.

[Manseej Khatri 2B]

Unless they give us the percent yield and ask us to find the actual yield (or we perform an experiment), the actual yield will likely be given.

[305614361]

In some questions, the yield is given to you, but when it isn't given they will always give you something to help find it

[Adrienne Yuh 2B]

Usually in the case of problems, it should be given to us as a percent or a straight value for us to calculate the theoretical yield.

[Nan_Guan_1L]

for most of the questions I've seen, they usually give you the actual yield, mass/molar mass, and some clues to find the actual chemical equations. with these, you could calculate the theoretical yield and there you get your yield percentage.

[Michelle Nguyen 3F]

Usually, the actual yield will be given to you while the theoretical yield will be calculated!

[Yolanda_Xing_3A]

Since we are not a lab course, actual yield are always given. It is not calculable anyhow.

[Grace_Remphrey_2J]

Given most of the practice problems in the textbook for this course, I would say they will give us the actual yield! If not, they would give you enough info (theoretical and percent yield) to be able to find it.
