When benzene C6H6 of 780 g of (Molar mass = 78 g/mol) combines with 750 mL of concentrated nitric acid (16 M) and 750 mL of sulphuric acid (18 M), 1000 g of nitrobenzene (molar mass = 123 g/mol) and 250 g of an unknown compound with a high boiling point are obtained now you need to identify the limiting reagent and compute the percent yield of nitrobenzene
