In a mixture of argon and hydrogen, occupying a volume of 1.54 L at 860.0 mmHg and 31.0 oC, the mass of the argon is 1.6 g. What is the partial pressure of argon?   41.3 mmHg   819 mmHg   491 mmHg   430 mmHg   369 mmH

A gas sample has an initial pressure of 593 mmHg and an initial volume of 0.511 L What is the pressure (in atm) when the volume of the sample is decreased to 244 mL? (Assume constant temperature and constant number of moles of gas.)

A weather balloon filled with helium has a volume of 106.0 liters when the temperature is 28.5 °C and the pressure is 765.6 torr. The balloon rises in the atmosphere to an altitude where the temperature is 9.2 °C and the pressure is 662.4 torr? What is the new volume of the balloon?

A sample of ammonia (NH3), a colorless gas with a pungent odor, occupies a volume of 3.00 L at a pressure of 655 mm Hg and a temperature of 25C. What volume, in liters, will this NH3 sample occupy at the same temperature if the pressure is increased to 725mm Hg?

A balloon is inflated to a volume of 8.5 L on a day when the atmospheric pressure is 765 mmHg. The next day, as a storm front arrives, the atmospheric pressure drops to 737 mmHg. Assuming the temperature remains constant, what is the new volume of the balloon, in liters?

A balloon is filled to a volume of 9.30L at a temperature of 27.1°C. If the pressure in the balloon is measured to be 2.20 atm, how many moles of gas are contained inside the balloon?

A gas-filled weather balloon has a volume of 52.0 L at ground level, where the pressure is 761 mmHg and the temperature is 23.2 °C. After being released, the balloon rises to an altitude where the temperature is -8.76 °C and the pressure is 0.0830 atm. What is the weather balloon's volume at the higher altitude? V= L

A sample of methane (CH4)has a volume of 26 mL at a pressure of 0.88 atmatm. What is the final volume, in milliliters, of the gas at each of the following pressures, if there is no change in temperature and amount of gas? Calculate the final volume for the sample at 0.28 atm
