• What is the volume occupied by 13.7 g Cl2lej at 45°C and 745 mmHg? • A 50.0 L cylinder contains nitrogen gas at a pressure of 12.5 atm. The contents of the cylinder are emptied into an evacuated tank of unknown voļume. If the final pressure in the tank is 1.55 atm, then what is the volume of the tank? • What is the pressure in kilopascals, exerted by 1.00 X 1020 molecules of N2 in a 305 ml flask at 175°C?" • A balloon is inflated to a volume of 2.50 L inside a house that is kept at 24°C. Then it is taken outside on a very cold wințer day. If the temperature outside is -25°C, what will be the volume of the balloon when it is taken outside? Assume the quantity of air in the balloon and its pressure both remain constant. • What is the density of oxygen gas (0,) at 298 K and 0.987 atm?
