please i need the answer ASAP

3.8. At 25C, an aqueous solution containing 35.0 wt% H2SO, has a specific gravity of 1.2563. A quantity of the 35% solution is needed that contains 195.5 kg of H2SO4 (a) Calculate the required volume (L) of the solution using the given specific gravity. (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 instead of the given specific gravity of the mixture. Also find the molar concentration
