Determine the molecular weights of the substances CuSO4, BaO, CaCo3, S, Ca (OH) 2, Mg, Fe2O, Br2, HCL.

CuSO4: M = 64 + 32 + 16 * 4 = 160 g / mol
BaO: M = 137 + 16 = 153 g / mol
CaCo3: M = 40 + 12 + 16 * 3 = 100 g / mol
S = 32 g / mol
Ca (OH) 2 = 40 + 16 * 2 + 1 * 2 = 74 g / mol
Mg = 24 g / mol
Fe2O 56 * 2 + 16 = 128 g / mol
Br2 = 160 g / mol
HCL = 36.5 g / mol
