Two aqueous sulfuric acid solutions containing 20.0 wt% H2SO4 (SG=1.139) and 60.0 wt% H2SO4 (SG=1.498) are mixed to form a 4.00 molar solution (SG=1.213).
(a) Calculate the mass fraction of sulfuric acid in the product solution?
(b) What feed rate of the 60% solution (L/h) would be required to produce 1250 kg/h of the product?
