The formula unit for this compound has a gram molar mass that is the sum of the gram atomic masses for its two constituent atoms, 22.989 + 35.483 = 58.472. Therefore, 2.1 g constitutes 2.1/58.472 = 0.0359 mole. Multiplying this number of moles by Avogadro's number, which is 6.022 X 1023, gives the number of atoms of sodium, 2.2 X 1022 atoms of sodium.
