A sample of oxygen gas occupies a volume of 6.35 L at 45.0C and 0.540 atm.

If it is desired to increase the volume of the gas sample to 9.22 L, while decreasing its pressure to 0.397 atm, the temperature of the gas sample at the new volume and pressure must be

A sample of krypton gas occupies a volume of 9.90 L at 60 C and 0.5140 atm. If the volume of the gas sample is increased to 11300 mL, while its temperature is increased to 119 C, the resulting gas pressure, in torr, will be
