Question:

What is the percent yield for a reaction in which 342g of a product is actually produced when the theoretical yield is 400g?

Proportions and Percentages:

When we have big-ish yield numbers such as 342 grams, it can be a bit unintuitive to understand how far off the number is from 400 grams, when you are sampling how much yield you had. In that case, we often use the per-unit system or percentage system to give the yield as a percentage of the expected yield.

We have the following:

  • the actual yield is {eq}\text{Actual} = 342\ \text{g} {/eq} .
  • the theoretical yield is {eq}\text{Theoretical} = 400\...
