Type your answer on the lines below, or write it out on paper.
Benzene is nitrated to form nitrobenzene, C6H5NO2.
C6H6 + HNO3 → C6H5NO2 + H2O
In an experiment, 15.6 g of benzene produced 18.45 g of purified nitrobenzene.
Calculate the percentage yield of nitrobenzene. Give your answer to 3 significant figures. (Ar: H = 1.0, C = 12.0, N = 14.0, O = 16.0)
