If the actual yield of NO is 2.18 g and the theoretical yield is 3.00 g, what is the percent yield?

Which statement correctly describes the relationship between the amount of reactant used and the percent yield in a chemical reaction?

Which of the following best describes how to calculate the theoretical yield in a chemical reaction?

What is the percent ionization of a 0.300 M solution of formic acid (HCOOH), given that Ka = 1.78 × 10^{-4}?

Which of the following factors are necessary to determine both the theoretical and actual yield in a chemical reaction?
