Benzene ( $C X_{6} H X_{6}$ , $78 g/mol$ ) is converted to nitrobenzene in $85%$ yield, and nitrobenzene is reduced to aniline ( $C X_{6} H X_{7} N$ , $93 g/mol$ ) in $70%$ yield. Starting with $39 g$ of benzene, the mass of aniline obtained is

Benzene = 0.5 mol. Overall yield = 0.85 x 0.70 = 0.595. Aniline = 0.5 x 0.595 = 0.2975 mol x 93 = 27.7 g.
