Change grams to mols for KCl.
Change 60.0 mL of 0.500 M solution CaCl2 to mols.
Write the ionization equation to show how the molecules break apart.
Note the mol ratios.
Calculate molarity which = #mols/L soln for each ion.
I don't think I've omitted a step but post your work if you get stuck.
A 3.50 g sample of KCl is dissolved in 10.0 mL of water. The resulting solution is then added to 60.0 mL of a 0.500 M CaCl2(aq) solution. Assuming that the volumes are additive, calculate the concentrations of each ion present in the final solution.

There is not much to it.
how many moles of KCl? That give you the mole Cl, moles of K from that.
How many moles of CaCl2? That gives you themoles of Ca, and 2Cl ions.
Now add the Cl ions from the calcium chloride, and the KCl.
Concentration Cl=moles Cl/total volume and so on.
