A pure H2SO4 (98 % by weight ) solution has a specific gravity of 1.8 the normality of the H2SO4 IS:(A) 9N (B) 18N(C) 72N (D) 36 N
98% wt% H2SO4 means 98 g in 100 ml solutionGiven density of Solution be 1.8 g/ml The volume of H2SO4 solution will be (100/1.8) =55.55ml NowMolecular weight of H2SO4= 98 g/mol In 100 g of solution the mol of H2SO4 will be 1 mol. i.e. 1mol in 55.55 ml so moles in 1 Lt will be 1"(1000)/55.55= 18 molar
