    Mass = 427.05 g

    Explanation:

    Given dа ta:

    Formula units of sodium chloride = 4.38 * 10²⁴

    Mass of NaCl = ?

    Solution:

    One mole contain formula units = 6.022 * 10²³

    4.38*10²⁴ formula units * 1mol / 6.022 * 10²³ formula units

    0.73 * 10¹ mol

    7.3 mol

    Mass of NaCl:

    Mass = number of moles * molar mass

    Mass = 7.3 mol * 58.5 g/mol

    Mass = 427.05 g
