WebAnswer (1 of 2): The use of “formula mass” is intended to avoid appying the misnomer “molecule” to ionic compounds. A molecule is an arrangement of atoms held together by covalent bonds. The exact number of each atom is clearly indicated by the molecular formula. For example, hydrazine (a rocket... WebThe answer will be the same either way. Total mass of 100 atoms = (18.7 x 10) + (81.3 x 11) = 1081.3. So relative atomic mass = 1081.3/100 = 10.8 to 3 significant figures. Note: You can't quote your answer to more than 3 significant figures because that is all the percentages are quoted to.
