A 3.50L gas sample at 20°C and a pressure of 86.7 kPa is allowed to expand to a volume of 8.00L. The final pressure of the gas is 56.7 kPa. What is the final temperature?

You have diaphragm pump that generates a 6.30 L internal volume when the diaphragm flexes. It is currently operating at 98.2oC. What is the pressure in atmospheres in the pump with each cycle? Estimate that exactly 1 mole=22.4L of air to determine the number of moles of gas in the pump. Assume air is behaving as an ideal gas.

NO2 is collected in a 250-mL container at 27°C. The pressure in the container is 216 kPa, what is the mass of the gas?
