Calculate activities of Ca2+ and F- and the solubility of fluorite (CaF2) in pure water at 25C without regard to possible hydrolysis. Assume that all activity coefficients are equal to one. Express the solubility of fluorite in terms of mol/L and g/L.

Answer 1

A temperature of 20o C is equivalent to approximately

Answer 2

if the volume of the vapor had been assumed to be 125ml instead of your measured volume,what would have been the percent error in your report? molar mass of the compound?explain
