a A sealed and initially empty container has a piston that allows for the volume to be adjustable. The volume is set to 2.50 L and the temperature of the system is maintained at a constant 73.0 C. Liquid water, neon gas, and helium gas are added in a sequence of steps outlined below. Once the water is added, assume that at all times there will be some liquid water with a negligible volume that remains at the bottom of the container. step 1: 5 mL of liquid water is injected into the container step 2: 1.75 g of neon is added. step 3: 35.6 mL of helium at 27.0 C and 326.5 kPa is added to the mixture. step 4: An additional 2 mL of liquid water is added. step 5: The piston is adjusted until the container volume is 1.25 L.
