    Given:

    T = 190 °C

    = 190 + 273

    = 463 K

    V = 2420 ml

    = 2.42 l = 0.00242 m^3

    P = 1 atm

    = 1.01325 * 10^5 N/m^2

    M = 2.04 g

    Using ideal gas law,

    P * V = n * R * T

    Number of moles, n = (1.01325 * 10^5 * 0.00242) : 8.314 * 463

    = 0.0637 mole

    Molar mass = mass/no of moles

    = 2.04 / 0.0637

    = 32.025 g/mol
