Dilute 250 ml of 98% concentrated sulfuric acid with a density of 1.84 g / cm3 to 600 ml. what is the concentration of concentrated sulfuric acid after dilution

Dilute 250 ml of 98% concentrated sulfuric acid with a density of 1.84 g / cm3 to 600 ml. what is the concentration of concentrated sulfuric acid after dilution

The mass of concentrated sulfuric acid is 1.84 * 250 = 460 G
The amount of H2SO4 is 460 * 98% / 98 = 4.6 mol
6 / 0. 6 = 7. 67 mol / L
