Solution: Using the generic expression to convert g to atoms: Number of Atoms = (Given Mass/Molar Mass) * Avogadro's Number Number of Atoms = (78/40.078) * 6.02 * 10^ {23} Number of Atoms = 1.9462 * 6.02 * 10^ {23} Number of Atoms = 1.171 * 10^ {+24} Therefore, there are various non-equivalent definitions of atomic radius. 29863 views Magnesium - Element information, properties and uses | Periodic Table Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. We are not permitting internet traffic to Byjus website from countries within European Union at this time. The atomic weight, molecular weight, or formula weight of one mole of the fundamental units (atoms, molecules, or groups of atoms that correspond to the formula of a pure substance) is the ratio of its mass to 1/12 the mass of one mole of C12 atoms, and being a ratio, is dimensionless. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. The standard of mass, the kilogram, is not precisely known, and its value appears to be changing.
