A rigid vessel of volume 10 m3 is filled with hydrogen at 25oC and 500 kPa. Due to leakage, some gas has escaped from the vessel until the pressure in the vessel drops down to 200 kPa, and the corresponding temperature of the gas inside the vessel is found to be 15oC. The amount of gas leaked (in kg) from the vessel is _________.
Answer: 2.30 to 2.40
