Calculating Theoretical Yield and Percent Yield

Adipic acid, \(\mathrm{H}_{2} \mathrm{C}_{6} \mathrm{H}_{8} \mathrm{O}_{4}\), used to produce nylon, is made commercially by a reaction between cyclohexane \(\left(\mathrm{C}_{6} \mathrm{H}_{12}\right)\) and \(\mathrm{O}_{2}\):

\(2\ \mathrm{C}_{6} \mathrm{H}_{12}(l)+5\ \mathrm{O}_{2}(g) \longrightarrow 2\ \mathrm{H}_{2} \mathrm{C}_{6} \mathrm{H}_{8} \mathrm{O}_{4}(l)+2\ \mathrm{H}_{2} \mathrm{O}(g)\)

(a) Assume that you carry out this reaction with  of cyclohexane and that cyclohexane is the limiting reactant. What is the theoretical yield of adipic acid? (b) If you obtain 33.5 g of adipic acid, what is the percent yield for the reaction?

Imagine you are working on ways to improve the process by which iron ore containing \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) is converted into iron:

                      \(\mathrm{Fe}_{2} \mathrm{O}_{3}(s)+3 \mathrm{CO}(g) \longrightarrow 2 \mathrm{Fe}(s)+3 \mathrm{CO}_{2}(g)\)

(a) If you start with  of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) as the limiting reactant, what is the theoretical yield of Fe?

(b) If your actual yield is , what is the percent yield?
