    Oxygen has a n atomic weight of 16 amu, ergo a mole of O_2 has a mass of 32g, and a molecular weight of 32 amu.

    And of course STP = volume used, 1 mol any gas = 22.4

    d=MM(P/RT) Ideal gas law.

    1 mole. of O2 = 32g. 1 mole. at STP occupies 22.4L. Density = Mass / Volume. Density of O2 at STP = 32g / 22.4L = 1.43g/L = 1.43kg/m³
