a) A water treatment plant adds chlorine (Cl2) to the water it supplies to a city at a rate of 2.8 x 10 mol/L. If the plant supplies 50 million gallons of water per day, calculate the amount of chlorine added to the water, daily (in kg/day). b) A chemical plant releases a pollutant into a river at a concentration of 0.02 mg/L. The river flow rate is measured to be 50 cubic meters per second. The plant releases the pollutant for a period of 8 hours each day. Determine the mass of pollutant released into the river each day (in kg/day). c) At 25C, a solution with 35 wt% H2SO4, has a specific gravity of 1.2563. For analysis that you are performing, you need a volume of the solution that contains 46.7 kg of H2SO4. What volume of the solution do you need?
