It is not always a whole number Relative Atomic Mass 2 of 9 the sum of the relative atomic masses of the atoms in the numbers shown in the formula Relative Formula mass 3 of 9 the relative formula mass of a covalent compound Relative Molecular Mass 4 of 9 the percentage of an element in a compound % by Mass 5 of 9 the number of atoms of an element or compound which have a certain mass a mole 6 of 9 mass (G) / R.A.M = Moles 7 of 9 moles * R.A.M = Mass (g) 8 of 9 mass (g) / moles = Relative Atomic Mass 9 of 9
