A mixture of xenon and hydrogen gas is expanded from a volume of 32.0 L to a volume of 62.0 L, while the pressure is held constant at 71.0 atm. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits. C kJ 10

A mixture of krypton and hydrogen gas is compressed from a volume of 68.0 L to a volume of 52.0 L, while the pressure is held constant at 82.0 atm. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits. O kJ x10

A mixture of helium and hydrogen gas is compressed from a volume of 81.0 L to a volume of 70.0 L, while the pressure is held constant at 34.0 atm. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits.

An expanding gas does 157 J of work on its surroundings at a constant pressure of 1.02 atm. If the gas initially occupied 68.0 mL, what is the final volume of the gas?
