1. Approximately how much calcium would you ingest by drinking eight 8-oz glasses of your local water. 1 oz=29.57mL
2. Assume an average minimum daily requirement for calcium is 1150 mg. Calculate what percentage of your daily requirements could be met by drinking 1.0L of your local water.
**In my calculation I have determined that the concentration of Ca ions in my water is .0022mol/L and my water hardness is 221 ppm CaCo3
