    To answer this item, we are to assume that dinitrogen oxide is an ideal gas such that it follows the equation,

    PV = nRT

    Taking into account the density of the gas,

    P = (m/M) RT/V

    Substituting the known values,

    P = (2.85 g/L) (0.0821 L. atm/mol K) (298 K) / 44 g/mol)

    P = 1.58 atm

    Each 1 atm is equal to 760 mmHg

    Answer: 1204.38 mmHg
