Two aqueous sulfuric acid solutions containing 20.0wt% H2SO4 SG 1:139 and 60.0wt% 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) Taking 100kg 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 1250kg/h of the product?

Question
Two aqueous sulfuric acid solutions containing 20.0wt% H2SO4 SG 1:139 and 60.0wt% 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) Taking 100kg 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 1250kg/h of the product?
