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). Only b is needed a.) Calculate the mass fraction of sulfuric acid in the product solution. b.) Taking 100 kg of the 20% feed solution as a basis, draw and label a flowchart of this process, labeling both masses and volumes, and do the degree-of-freedom analysis. Calculate the feed ratio (liters 20% solution/liter 60% solution). c.) What feed rate of the 60% solution (L/h) would be required to produce 1250 kg/h of the product?
