    2.21*10²³molecules

    Explanation:

    Hello,

    The question requires us to calculate the number of molecules present in a given number of mole.

    Numbe of mole = 0.3672 moles

    According to mole ratio concept, one mole of any substance is equal to Avogadro's number of particles, atoms or molecules. I. e,

    1 mole = Avogadro's number

    Avogadro's number = 6.022*10²³ atoms/molecules/particles or ions

    1 mole = 6.022*10²³molecules

    0.3672 mole = x molecules

    x = 0.3672 * 6.022*10²³

    X = 2.21*10²³molecules

    Therefore, 0.3672moles of LiBr contains 2.21*10²³molecules
