    The number of moles of gas present are 0.0054

    Explanation:

    Given-

    Temperature, T = 100°C = 100 + 273 = 373K

    Volume, V = 0.044L

    Pressure, P = 3.81 atm

    Moles of gas, n = ?

    We know,

    PV = nRT

    R = 0.082 L. atm. K⁻¹. mol⁻¹

    n = PV/RT

    n = (3.81) (0.044) / (0.082) (373)

    n = 0.0054 moles

    Therefore, number of moles of gas present are 0.0054
