    Mass percentage of a solution is the amount of solute present in 100 g of the solution.

    Given dа ta:

    Mass of solute H2SO4 = 571.3 g

    Volume of the solution = 1 lit = 1000 ml

    Density of solution = 1.329 g/cm3 = 1.329 g/ml

    Calculations:

    Mass of the given volume of solution = 1.329 g * 1000 ml/1 ml = 1329 g

    Therefore we have:

    571.3 g of H2SO4 in 1329 g of the solution

    Hence, the amount of H2SO4 in 100 g of solution = 571.3 * 100/1329 = 42.987

    Mass percentage of H2SO4 (%w/w) is 42.99 %
