Th e volume of a gas at 75 kPa is 4.0 L. What is the volume of the gas if the pressure increases to 100.0 kPa? Assume the temperature and amount of gas are constant.

247.2 liters of gas has a pressure of 128.02 kPa at 57.5 C.  If the pressure increases to 577.0 kPa and the temperature to 147.6 C, what would be the new volume of the gas?

A sample of gas occupies 782. mL at standard pressure. What volume will the gas occupy at a pressure of 520. mm Hg if the temperature remains constant?

0.0380g of Mg strip reacted completely with 6 M HCl in the gas buret of 35.8 mL oh hydrogen gas is collected over water at 20.0 degrees C. The pressure of the "wet" hydrogen gas is adjusted to the outside atmospheric pressure, a pressure of 747.50 torr. The wapor pressure of water at 20.0 degrees C is 17.54 torr.  Using the volume of hydrogen gas collected and the universal gas law, PV=nrt, where r=0.08206 L x atm/mol x K, calculate the experimental number of moles of hydrogen produced.

A mixture of gases contains: 2.70 g He, 8.13x1022 atomsof Ne, and 0.180 mol Ar. If the total pressure of themixture is 10.0 atm, what are the partial pressures ofthe gases in the mixture?

A gas occupies 17 L at a pressure of 102.3 kPa and 299 K. If the gas is cooled to 250 K and the pressure is lowered to 85.0 kPa, what will the new volume be?

A high-altitude balloon contains 15.7 L of helium gas at 101.3 kPa. What is the volume when the balloon rises to an altitude where the pressure is only 15.0 kPa? (Assume there is no change in temperature.)

If a gas occupies a volume of 0.550 L at 25°C, at what temperature, in °C, will it occupy a volume of 1.500 L if the pressure remains constant?

If a gas filled balloon has a volume of 1 Liter at ten feet underwater, would you predict the volume of the balloon to be greater than, less than, or the same as 1 Liter when it is brought up to the surface? Why? Assume constant temperature.

A sample of gas has a volume of 0.4 L at 293 K.What is the volume of the gas at 523 K, assuming thatthe pressure and amount of gas remain constant?
