A solvent solution entering a process must be exactly 50% saturated to cleanse the product at the correct rate. The solvent solution enters a mixer as a concentrate at 80% saturation, is diluted with distilled water, and then sent to the reactor. If we are using 600 m3/hr of diluted solvent through the process, how much concentrated solvent is used per hour? Show all of your work and use the correct units to receive full credit.
