A vertical cylinder-piston device contains a fixed mass of gas in equilibrium. The cross-sectional area of the piston is 0.05 m2. For 150 kPa pressure of the gas in the cylinder, the mass of the piston is _______ kg (round off to 2 decimal places). Assume that the atmospheric pressure is 100 kPa and the acceleration due to gravity is 9.81 m/s2.
Answer: 254.00 to 255.00
