Two aqueous sulfuric acid solutions are available at a processing facility: a. 20.0 wt% H2SO4 (sg = 1.139) b. 60.0 wt% H2SO4 (sg = 1.498) It is desired to mix the two solutions such that the final product has a concentration of 4.00 M (sg = 1.213). There is 100 kg of the 20% solution available. If all of this is to be used, calculate: a. The mass of 60% solution needed b. The mass and composition of the final product
