The internal pressure on a bottle of soda is 5560 torr. The bottle cap is designed to withstand a pressure of 7.3 atm. Calculate the pressure in psi.

A student is told the barometric pressure is known to be 1.13 atm. In her experiment she collects hydrogen gas in a graduated cylinder as described in this experiment. She finds the water level in the graduated cylinder to be 7.7 cm above the surrounding water bath.  What is the total pressure inside the graduated cylinder in torr?

A sealed cannister holds three gases: oxygen, carbon dioxide, and helium. The partial pressures of the three gases are 2.65atm, 2.76atm, and 3.31atm, respectively. Calculate the total pressure inside the cannister.

A weather balloon is inflated with helium to a volume of 895.0 L at sea level, where the temperature is 30.0 °C and the barometric pressure is 760.0 torr. The balloon rises to an altitude of 4500.0 feet where the pressure is 645.0 torr and the temperature is 6.0 °C. What is the change in volume (in liters) of the balloon in going from sea level to 4500.0 feet?

The barometric pressure is 750.8 torr. The water vapor pressure at the temperature at which the experiment is conducted is 21.711 torr. Determine the partial pressure of the gas in torr. Give your answer to the correct number of significant figures.

A sample of an unknown compound is vaporized at 120. °C. The gas produced has a volume of 1850. mL at a pressure of 1.00 atm, and it weighs 1.95 g. Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Be sure your answer has the correct number of significant digits. g mol x10 X

A tank contains 115 moles of neon gas. It has a pressure of 57 atm at a temperture of 45 celsius. Calculate the volume of the tank.

Boron trifluoride gas is collected at 6.0 °C in an evacuated flask with a measured volume of 15.0 L. When all the gas has been collected, the pressure in the flask is measured to be 0.140 atm . Calculate the mass and number of moles of boron trifluoride gas that were collected. Be sure your answer has the correct number of significant digits. mass: g x10 mole: | mol ?

A mixture contains O2 at 700. torr pressure, F2 at 600. torr pressure, and Cl2 at 400. torr pressure. What is the total pressure of the gases in the system?

A sample of nitrogen gas at a pressure of 888 torr and a temperature of 24.4°C, occupies a volume of 646 mL. If the gas is compressed at constant temperature until its pressure is 1050 torr, the volume of the gas sample will be mL.
