A sample of water has its hardness due to only CaSO_(4). When this water is passed through on anion exchange resin, SO_(4)^(2-) ions are replaced by OH^(-). A 25.0 mL sample of water so treated requires 21.58 mL of 10^(-3) MH_(2)SO_(4) for its titration. What is the hardness of water expressed in terms of CaCO_(3) in ppm? Assume density of water 1.0g//mL.
