1. 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.
