Solubility Calculations

a). What is the total amount (in mol) of KCl that can be dissolved in 1 L of pure water? Using the thermodynamic information provided from an outside source, determine the equilibrium constant. Then compute the equilibrium concentration for the ions in solution. In your calculation, ignore activity coefficients (i.e. assume they are 1), and assume that the ions do not form other complexes in solution.

b.) What changes if you consider the effect of activity coefficients? Can you still do the calculation? If yes, how; if no, why not? Discuss how it affects the result in part a.
