1. A sample of gas with an initial volume of 28.2 L at a pressure of 728 mmHg and a temperature of 301 K is compressed to a volume of 14.9 L and warmed to a temperature of 375 K. What is the final pressure of the gas?
2. A gas sample with a volume of 5.3 L has a pressure of 725 mmHg at 24C. What is the pressure of the sample if the volume remains at 5.3 L but the temperature rises to 88 âC?
3. What is the volume occupied by 0.256 mol of helium gas at 1.20 atm and 303 K ?
4. A cylinder contains 28.5 L of oxygen gas at a pressure of 1.6 atm and a temperature of 300 K . How many moles of gas are in the cylinder?
Express your answer using two significant figures.
5. An experiment shows that a 266 mL gas sample has a mass of 0.428 g at a pressure of 765 mmHg and a temperature of 30 âC. What is the molar mass of the gas?
