    18.066 * 10²³ particles

    Explanation:

    Given dа ta:

    Number of moles of Sn = 3 mol

    Number of representative particles = ?

    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,

    18 g of water = 1 mole = 6.022 * 10²³ molecules of water

    1.008 g of hydrogen = 1 mole = 6.022 * 10²³ atoms of hydrogen

    For 3 mole of Sn:

    3 * 6.022 * 10²³ particles

    18.066 * 10²³ particles
