    At STP (which is standard temperature (0 deg C) and pressure (1.0 atm)) 1 mole of any ideal gas occupies a volume of 22.4 L.

    molar mass I2 = 253.8 g/mol

    So at STP 22.4 L of I2 has a mass of 253.8 g

    density = mass / volume

    = 253.8 g / 22.4 L

    = 11.3 g/L

    For questions not at STP you can use this equation

    Density = PM/RT

    eg, for your question

    P = pressure (1.0 atm)

    M = molar mass (253.8 g/mol

    R = gas constant (0.082057 L atm mol^-1 K^-1)

    T = temperature (273.15 K)

    d = 1.0 atm x 253.8 g/mol / (0.082057 x 273.15K)

    = 11.3 g/L
