QUESTION: 7

A commercial gas cylinder contains 75 L of helium at 15 bar (gauge pressure). Assuming ideal gas behaviour for the isothermal expansion, how many 3.0 L balloons at a pressure of 1.1 bar can be filled by this gas in this cylinder?

Solution:
QUESTION: 8

A 1.10 L flask containing nitrogen at a pressure of 710.0 torr is connected to an evacuated flask of unknown volume. The nitrogen, which acts ideally, is allowed to expand into the combined system of both flasks isothermally. If the final pressure of the nitrogen is 5809.0 torr, volume of the evacuated flask is

Solution:
QUESTION: 9

Nitrogen dioxide (NO2) cannot be obtained in a pure form in the gas phase at exists as a mixture of NO2 and N2O4. At 298 K and 0.98 atm, the density of this gas mixture is 2.764 g L-1, Thus partial pressure of NO2 in the mixture is

Solution:
