How many grams of Cl are in 305 g CaCl2 ?

I am confused on how to start, but I found the molar mass of Ca is 40.08, Molar mass of Cl 2 is 70.906. I added those together to get 110.986.
I don't know the next step to incorporate 305g

mols CaCl2 = grams CaCl2/molar mass CaCl2.
Then mols Cl is twice that since there are two mols Cl for every 1 mol CaCl2.
