During the synthesis of a pharmaceutical precursor, a theoretical stoichiometry calculation indicated that 3.20 kg of the compound should be produced.
After recrystallisation and drying, the actual mass of the purified precursor recovered was 2496 g.
Calculate the percentage yield of the precursor.
