The volume and temperature of air (assumed to be
an ideal gas) in a closed vessel is 2.87m³ and 300
K, respectively. The gauge pressure indicated by a
manometer fitted to the wall of the vessel is 0.5
bar. If the gas constant of air is R = 287 J/kg K and
the atmospheric pressure is 1 bar, the mass of air
