Question 1: Alkaline water from a well in Lane County, Oregon contains carbonate (CO32-) at 10 mg/L and bicarbonate (HCO3-) at 296 mg /L. What is the total carbon concentration in mg C/L?

Question 2: The same well water contains dissolved calcium (Ca), magnesium (Mg), sodium (Na) and potassium (K) at 5.0, 1.0, 136 and 1.2 mg/L, respectively. Determine these concentrations in units of mol/L.

Question 3: Determine the hardness of this water in units of mg/L as CaCO3. Hardness is the sum of the concentrations of multivalent cations in the water, which in this case include Ca (as Ca2+) and 1.     Mg (as Mg2+). Hardness is expressed in "equivalent" units or "CaCO3" units.
