M_(CaSO_4)= 136.13400 g/(mol)

Explanation:

You must add the molar masses, which are the atomic weights of each atom in the compound. Note that since there are 4 Oxygen atoms, the molar mass of oxygen was added 4 times.

M_(CaSO_4) = 40.078g/(mol) + 32.06g/(mol) + 4 * 15.999g/(mol)
= 136.13400 g/(mol)
