    44.8 L

    Explanation:

    1 mole of a gas at s. t. p. occupies a volume of 22.4 L.

    Molar mass of Neon is 20.1 g/mol

    Number of moles of neon present in 40.2 g = Mass/molar mass

    Number of moles = 40.2 / 20.1 = 2 moles.

    Therefore, 2 moles of neon gas will occupy 2 * 22.4 L = 44.8 L
