A sulfuric acid solution containing 571.3 g of h2so4 per liter of aqueous solution has a density of 1.329 g/cm3. Part a calculate the mass percentage of h2so4 in this solution. Express your answer using four significant figures. G

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 %
