    Answer: 1.93 x 10^24 molecules

    Explanation:

    CH4 is the chemical formula for methane, the first member of the alkane family.

    Based on Avogadro's law:

    1 mole of any substance has 6.02 x 10^23 molecule

    So, 1 mole of CH4 = 6.02 x 10^23 molecules

    3.2 moles of CH4 = Z

    To get the value of Z, cross multiply:

    (Z x 1 mole) = (6.02 x 10^23 molecule x 3.2 moles)

    Z•mole = 19.26 x 10^23 molecules•mole

    Divide both sides by 1 mole

    Z•mole / 1 mole = 19.26 x 10^23 molecules•mole / 1mole

    Z = 19.26 x 10^23 molecules

    Place Z in standard form

    Z = 1.93 x 10^24 molecules

    Thus, 3.2 moles of ch4 has 1.93 x 10^24 molecules
