To find molar mass, you first need to determine the atomic mass of the elements you are calculating for. I will use S5O2 as my example.
S5O2 has a molar mass of 192.324. The first step is to determine the atomic mass of both S (sulfur) and O (oxygen). The atomic mass is most commonly found under the element symbol, or just recognize it as the number with decimal places.
The atomic mass of Sulfur is 32.065. The atomic mass of Oxygen is 15.999. The next step is to multiply the atomic mass by the number of atoms that the compound has. So, for S5O2, you would multiply 32.065 five times. Then you would multiply 15.9994 twice. This would give you 160.325 + 31.998 which equals 192.324.
