    Answer:

    The required volume is 0.84 L

    Explanation:

    Given,

    Mass of O2 gas = 1.20 g

    We know,

    At STP, molar volume of all gases is 22.4 L

    and Molar mass of O2 gas is 32 g

    Now,

    Number of moles = mass/molar mass

                                  = 1.20/32

                                  = 0.0375

    Again,

    At STP,

    Number of moles = Volume/Molar volume

    or, Volume = Number of moles X Molar Volume

    or Volume = 0.0375 X 22.4

    ∴ Volume = 0.84 L

    So, the required volume is 0.84 L
