On the flow sheet below, two hydrocarbon streams(A and B) of different composition are combined in a mixer to formstream C which will be sent for further refining. Stream A is knownto contain 60 mass% C6 and 40 mass% C8 hydrocarbons, while stream B contains 50 mass%C6 and 50 mass%C8 hydrocarbons. If 200kg of A and 100 kg of B are mixed per minute,
(a) How manykilograms of mixture C are produced per minute?
(b) What is the composition of mixtureC?
