    Answer;

    = 5.1 g/L

    Explanation;

    Using the equation;

    PV = nRT, where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol-1.

    Number of moles is 1 since one mole has a mass equivalent to the molar mass.

    Therefore; We can find the volume and thus get the density.

    V = nRT/P

    = (1 * 0.08206 * 237) / 3.510

    = 5.5408 L

    Hence; Density = mass/volume

    = 28.26 g/5.5408 L

    = 5.1 g/L

    The Density is 5.1 g/L or 0.005 g/cm³
