At 25 degree centegrade, an aqueous solution containing 35.0 wt% H2SO4 has a specific gravity of 1.2563. A quantity of the 35% solution is needed that contain 195.5kg of H2SO4. Calculate the required volume (L) of the solution using the given specific gravity. Estimate the percentage error that would have resulted if pure-component specific gravities of H2SO4 (SG = 1.8255) and water had been used for the calculation instead of the given specific gravity of the mixture.
