How many grams of Cl are in 205 g of CaCl2?

I believe, that you would take the molar mass of 2Cl and divide it by 205g, and multiply it by 100 to determine the mass percent of Cl within the compound.

you need to find the fraction of cl in the given compound then multiply with the given mass.(2Cl/CaCl2)x205g. (69/109)x205g=129.8g of cl
