Congress banned the production of the speedy dry cleaning company's dry cleaning fluid in 2000. Speedy is using a new cleaning fluid. The new dry cleaning fluid has one-sixth the volatility of the former dry cleaning fluid. The density of the new fluid is 1.6220g/mL. Assume that the amount of residue is the same as the resulting from the use of the old fluid and estimate the mass emission rate to the atmosphere in kg/mo. Because the new dry cleaning fluid is less volatile, the company will have to purchase less per year. Estimate the annual volume of dry cleaning fluid saved in m3/yr.
