    mass of CH4 = 14

    Molecular mass of CH4 16.04gmol

    No of mole of CH4 = 14/16.04

    No of mole of CH4 = 0.8728mol

    Stoichiometrically, from the above

    2 Molecules of Hydrogen will produce 1molecule of methane

    Therefore, 2*0.8728 mole of Hydrogen will produce 0.8728mol of Methane.

    The no of molecule of hydrogen is 1.7456
