Question: The Lena Chemical Co. concentrates leftover acids from various chemical processes. Leftover acid from a nitrating process contains 24.0% nitric acid (HNO3), 55.0% sulfuric acid (H2SO4), and 21.0% water (H2O). This acid is to be concentrated (strengthened in acid content) by adding sulfuric acid with 92.0% H25O4 and nitric acid containing 89.0% HNO3. The final product is to contain 31.0% HN03 and 58.0% H2SO4. Compute the mass of the initial acid solution and the mass of the concentrated acids that must be combined to produce 2.00(103) lbm of the desired mixture.
