Question - One of the main components of hard water is CaCO3. When hard water evaporates, some of the CaCO3 is left behind as a white mineral deposit. If a hard solution is saturated with calcium carbonate, what volume of the solution has to evaporate to deposit 19.7 mg of CaCO3? Ksp of CaCO3 is 4.96x10^-9.
I have no thought how to do this thank you for your help
