    Given dа ta:

    Number of moles of Al = ?

    Number of particles of Al = 1.204 * 10²⁴

    Solution:

    The given problem will solve by using Avogadro number.

    It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

    The number 6.022 * 10²³ is called Avogadro number.

    For example,

    one mole of Al = 6.022 * 10²³ particles

    1.204 * 10²⁴particles * 1 mol / 6.022 * 10²³ particles

    0.2 * 10¹ mole

    2 moles
