N -phenylethanamide, historically used as a painkiller, can be synthesised from benzene as shown. The overall yield for the synthesis of $$\(N\)$$-phenylethanamide from benzene was found to be $$\(35.2 \%\)$$. Calculate the minimum volume of benzene, in $$\(\mathrm{cm}^{3}\)$$, required to make 10.0 g of N -phenylethanamide. [Density of benzene $$\(=0.879 \mathrm{~g} \mathrm{~cm}^{-3}\)$$ ] (4)
