    The gas sample consists of CH₄ and He.

    Number of CH₄ moles - 4 g / 16 g/mol = 0.25 mol

    molar volume is where 1 mol of any gas occupies a volume of 22.4 L

    Therefore 0.25 mol of CH₄ gas occupies a volume of 22.4 L/mol x 0.25 mol

    Volume of methane - 5.6 L

    Number of He moles - 2.00 g / 4 g/mol = 0.5 mol

    Volume occupied by He - 22.4 L / mol x 0.5 mol = 11.2 L

    The total volume of the sample = 5.6 L + 11.2 L = 16.8 L
