Question: Two liquids, A and B, are mixed together. A is 3.0% solids, the remainder water. Bis 8.0% solids, the remainder water. An amount S of pure, dry solids is mixed with A and B to form 2.0(102) kg of a mixture with 5.0% solids. Develop a table of combinations of amounts of A, B, and S that will satisfy the final mixture requirements. What is the maximum amount of B that can be used to meet the requirements without having to remove pure, dry solids from the mixture? Hint: Write a short computer program or use a spreadsheet and start with B = 0 and increase in increments of 2 kg.
