Finding the Molar Mass of an Element
The steps of how to find molar mass of an element is surprisingly simple. Just take a look at the periodic table, find the element in question, and locate the atomic mass of that element. The atomic mass is equal to the molar mass of the element in grams per mole. For example, the atomic mass of carbon would be 12.01 grams per mole, because its atomic mass is 12.01.
Of course, in elements that only exist in nature as two or more bonded atoms, the number of atoms will have to be taken into account. For example, hydrogen does not occur in nature as just one atom, only has the diatomic H2, or two hydrogen atoms bonded together. Therefore, the molar mass of hydrogen would be 1.01 X 2, or 2.02 grams per mole. The same would hold true for oxygen, nitrogen, flourine, bromine, chlorine, and iodine, all of which only exist as two bonded atoms. Additional exceptions include phosphorus, which is made up of four atoms (P4), and sulfur, which is made up of eight atoms (S8).
