A solution is 0.126 M in KCl, 0.197 M in NaCl, and 0.148 M in MgCl2. What are the molarities of K + (aq), Na+ (aq), Mg2+ (aq), and Cl- (aq) in the solution? Hint: these are all ionic solutes and the salts fully dissociate into ions. Add up the concentrations of each ion that stem from each individual salt and then add them up as appropriate.
