Chemistry HELP AGAIN!

What is the total molar concetration of all the ions in 0.015 M solutions of the following salts in water?
.015 M KCl
.015 M CuSO4
.015 M CaCl2

KCl ionizes 100%; therefore,
KCl ==> K^+ + Cl^
There is 1 K in KCl so (K^+) = 0.015M.
There is 1 Cl in KCl so (Cl^) = 0.015
Total concn ions = 0.015 + 0.015 = ??
CuSO4 ==> Cu^+2 + SO4^2
CaCl2 ==> Ca^+2 + 2Cl^
Someone will check your answers if you wish to post them.
