What you have to do is find a periodic table and add the mass of each atom that the compound is made of.
Ca = 40.1
O = 16.0
H = 1.01
keep in mind that you have to also account for how many atoms of each there are in the molecule. for example, in Ca (OH) 2, there are one Ca, two O and two H
so the molar mass of Ca (OH) 2 = 40.1 + (2 x 16.0) + (2 x 1.01) = 74.12 g/mol
