Nitrobenzene,C₆H₅NO₂ , an important raw material for the dye industry, is prepared from benzene, C₆H₆(molar weight 78.1 g/mol), and nitric acid, HNO₃ according to the following chemical equation:
C₆H₆(l)+HNO₃(l)-----> C₆H₅NO₂(l)+H₂O(l)
a. When 23.2 g of benzene and an excess of nitric acid are used, what is the theoretical yield of nitrobenzene (molar weight 123.1 g/mol)? Theoretical yield= g
b. If 32.3 g of nitrobenzene is recovered, what is the percentage yield? Percentage yield = %
