A cylinder 1.00 m tall with inside diameter of 0.120 m is used to hold acetylene gas (molecular mass 26.04 g/mol) for welding. It is initially filled with gas until the gauge pressure is 1.30 x 106 Pa and the temperature is 22.0°C. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure is 2.00 x 106 Pa. Calculate the mass of acetylene that has been used.
