A 15 wt% NaSO4 solution is fed at the rate of 12 lb/min into a mixer that initially holds 100 lb of a 50-50 mixture (by weight) of NaSO4 and water. The exit solution leaves at the rate of 12 lb/min. Assume uniform mixing, which means that the concentration of the exit solution is the same as the concentration in the mixer. What is the total mass in the mixer at the end of 10 minutes? What is the concentration of NaSO4 in the mixer at the end of 10 minutes?
