Calculate the molarity of a solution that is prepared by dissolving 23.35g of CaCl2 in a sufficient amount of water to make a 600 mL solution

M = mols/L of solution.
You can calculate mols from mols = grams/ molar mass.
You know molar mass CaCl2 and you know grams. Calculate mols from equation 2, and substitute in equation 1 to calculate molarity.
Post your work if you need more help.
I left a message for you on the H2O2 problem posted earlier. 
No, that was rachel.

find molar mass H2O

23.5x1mol/110.08=0.2134
