Chapter 11, Problem 70QP(choose chapter or problem)
Problem 70QPExcessive levels of nitrates found in drinking water can cause serious illness. When nitrates are converted to nitrites in the body, the nitrites can interfere with the oxygen-carrying capacity of the blood, causing blueness of the skin. The EPA has determined that the maximum safe level of nitrate ion in water is 10 ppm. Suppose a sample of tap water was determined to have a nitrate ion concentration of 95 ppb. Assume the density of the solution is 1.00 g/mL.
(a) What is the concentration of nitrate ion in units of ppm? Is it safe to drink?
(b) What is the concentration of nitrate ion in units of mg/mL?
(c) What mass of nitrate ion is in 100.0 mL of this drinking water?
(d) How many moles of nitrate ion are in 100.0 mL of the water?
