Q1-A liquid adhesive, which is used to make laminated boards, consists of a olymer dissolved in a solvent. The amount of polymer in the solution has to be carefully controlled for this application. When the supplier of the adhesive receives an order for 3000 kg of an adhesive solution containing 13 wt% polymer, all it has on hand is (1) 500 kg of a 10 wt% solution, (2) a very large quantity of a 20 wt% solution, and (3) pure solvent. Calculate the weight of each of the three stocks that must be blended together to fill the order. Use all of the 10 wt% solution. A = 500 kg mass fr polymer 0.10 solvent 0.90 P kg B kg polymer 0.20 mass fr polymer 0.13 solvent 0.87 solvent 0.80 mass fr. pure solvent 1.00 mass fr C kg Blending
