3. Mass loading and concentration calculations a. (10 pts.) What mass

3. Mass loading and concentration calculations a. (10 pts.) What mass of ammonium sulfate (NH4)2SO4 must you add to water to make a 1.50 L solution that is 0.045M ? Answer: b. (10 pts.) Suppose 1.50L of a solution with a mass concentration of 45mg/L of some salt is left uncovered in a warm dry room. If, after a week, the volume has dropped to 0.45L due to evaporation, what is the final concentration? Answer: c. (10 pts.) A treatment plant discharges a wastewater flow to a lake. If the flow is 3.550 million gallons per day and the concentration is 25.00mg/L of Nitrate (NO3), what is the annual mass loading of total Nitrogen (N) (in lb/yr )
