answer both question write neatly

A sample of helium gas at 320 K and 0.974 atm K occupies a volume of 2.34 L. If the pressure of the gas is increased, while at the same time it is cooled to a lower temperature, the final gas volume could be larger or smaller than 2.34 L depending on the final pressure and temperature. O will be larger than 2.34 L. O will be smaller than 2.34 L. 0.647 mol sample of oxygen gas at a temperature of 18.0 C is found to occupy a volume of 27.2 liters. The pressure of this gas sample is mm Hg. A sample of helium gas collected at a pressure of 454 mm Hg and a temperature of 305 K has a mass of 5.48 grams. The volume of the sample is L. A 39.8 gram sample of xenon gas has a volume of 867 milliliters at a pressure of 2.68 atm. The temperature of the Xe gas sample is C
