Dilute the concentrated sulfuric acid with density of 1.84 g / cm3 and mass fraction of 98% to dilute sulfuric acid with density of 1.20 g / cm3 and mass concentration of 2 mol / L. calculate: (1) the volume of concentrated sulfuric acid required; (2) the volume of water required

(1) The concentration of concentrated sulfuric acid is C = 1000 ρ WM = 1000 × 1.84 × 98% 98mol / L = 18.4mol/l, if the volume of concentrated sulfuric acid is V, then V × 18.4mol/l = 1L × 2mol / L, v = 1L × 2mol / L 18.4mol/l = 0.11l, a: the volume of concentrated sulfuric acid is 0.11l
