Question

2.4 moles of NO, 2.4 moles of Oz, and 2.4 moles of H2O react

to form 2.0 moles of HNO3. What is the percent yield of this
reaction?

Answer 1

The idea here is that a reaction's percent yield tells you how many moles of a product will actually be produced by a chemical reaction for every

100

moles of this product that could theoretically be produced by the reaction.

In your case, the reaction is said to have a percent yield of

30

%

. This means that for every

100

moles of a product that the reaction could produce, you will only get

30

moles.
