Keep in mind, however, that the formula for an ionic compound does not represent the composition of a discrete molecule, so it may not correctly be referred to as the molecular mass.. Example 2: Look up the molecular weight of Carbon, 12.0107; Oxygen, 15.9994; and Hydrogen, 1.0079. This means the units will cancel each other out when you solve the equation. The given number of moles is a very small fraction of a mole (~104 or one-ten thousandth); therefore, we would expect the corresponding mass to be about one-ten thousandth of the molar mass (~0.02 g). The latter amount is most convenient and would simply involve the use of molar masses instead of atomic and formula masses, as demonstrated Example \(\PageIndex{2}\). A bag of fertilizer contains 500g of ammonium sulfate, ( N H X 4) X 2 S O X 4, and 500g of potassium nitrate, K N O X 3.
