At 25 degres C, an aqueouse solution containing 35.0 wt% H2SO4 has a specific gravity of 1.2563. A quantity of the 35% solution is needed that contains 195.5kg of H2SO4
B) 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 insteead of the given specific gravity of the mixture.
