A gas is stored in a vessel (Volume 1 m3). This vessel is placed inside a chamber. Two pressure gauges are installed, one on vessel and another on chamber. Gauge pressure reading of vessel gauge is 2 × 105 Pa and Gauge pressure reading of chamber gauge is 1 × 105 Pa. Calculate the mass of the gas. (Assume the temperature to be constant)
Ambient condition: Pamb = 1 × 105 Pa, Tamb = 25°C
Characteristic gas constant = 0.287 kJ/kgK
