Problem: A 35.3 g sample of solid CO2 (dry ice) is added to a container at a temperature of 100 K with a volume of 4.2 L.If the container is evacuated (all of the gas removed), sealed, and then allowed to warm to room temperature T = 298 K so that all of the solid CO2 is converted to a gas, what is the pressure inside the container?
