1. An ideal gas at a pressure of 4120 kPaa and a temperature of 25 °C is contained in a cylinder with a volume of 20 m³. A certain amount of the gas is released so that the pressure in the cylinder drops to 1730 kPaa. Expansion of the gas is isentropic. The heat capacity ratio is 1.4 and the gas constant is 0.286 kJ/kg-ºC. Determine the mass of gas remaining in the cylinder, in kg.
