A perfectly conducting vessel of volume,

V = 0.4 m^{3}

contains an ideal gas at constant temperature,

T = 273 K

. A portion of the gas is let out and the pressure of the gas falls by,

Δ p = 0.24 atm

. (Density of the gas at

STP

is

ρ = 1.2 kg m^{- 3}

). Find the mass of the gas which escapes from the vessel.
