Problem
An LPG (liquefied petroleum gas) cylinder weighs 14.8 kg when empty, when full, it masses 29.0 kg and shows a pressure of 2.5 atm. In the course of use at 27°C, the mass of full cylinder is reduced to 23.2 kg. Find out the volume of the gas in cubic metres used up at the normal usage conditions and the final pressure inside the cylinder. Assume LPG to be *n*-butane with normal boiling point of 0°C.
