### % yield

when calculating the % yield, can we use the theoretical yield that we calculated to get the actual yield or will that always be given? If so, how?

Thank you!

### Re: % yield

To my understanding, actual yield is what we would find in a lab environment physically conducting the reaction. With the context of a problem, we would probably be asked to find the theoretical yield and be given the actual yield to find the % yield. Hope this helps.

### Re: % yield

If we are asked to find a solution from a limiting reactant problem, for example, we will most often be evaluating the theoretical yield unless the problem explicitly states otherwise. Actual yield is what we get from the experiment that was conducted and will be less than the theoretical yield unless there are special circumstances.

### Re: % yield

I think you can never get an exact actual yield just using a theoretical yield since an actual yield is what comes from the lab and generally will vary depending on who does the experiment and the outside conditions.

### Re: % yield

the actual yield must be a given value or a value found from an experiment! if you're asked to find the %yield, the question will typically give you the actual yield value

### Re: % yield

The actual yield is normally listed in the problem and you're asked to find the theoretical yield through solving a stoichiometry problem. Once you have these two, you'll be able to solve for the percent yield.
