Asample of gas occupies a volume of 57.7 ml. as it expands, it does 128.5 j of work on its surroundings at a constant pressure of 783 torr. what is the final volume of the gas?

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
