Answer»

Right choice is (c) 48

To explain I WOULD say: 1 mole of SULFUR, S8 requires 48 moles of concentrated nitric ACID. The reaction is GIVEN byS8 + 48HNO3 → 8H2SO4 + 48NO2 + 16H2O. 10, 4 and 20 moles of concentrated nitric acid is required to produce iodic acid, carbon dioxide and phosphoric acid from 1 mole of iodine, carbon and phosphorus, RESPECTIVELY.
