A water sample is found to contain `96 p p m` of `SO_(4)^(2-)` and `122 p p m` of `HCO_(3)^(ɵ)` with `Ca^(2+)` ion as the only cation.  a. Calculate the p p m of `Ca^(2+)` in water.  b. Calculate the mol of `CaO` required to remove `HCO_(3)^(ɵ)` ion form `1000 kg` of the water  c. Calculate the concetrated of `Ca^(2+)` in `p p m ` remaining in water after adding `CaO`.
