A 270-mL gas sample contains argon and nitrogen at a temperature of 58∘C. The total pressure of the sample is 720 mmHg and the partial pressure of argon is 236 mmHg. What mass of nitrogen is present in the sample?

A mixture of nitrogen, oxygen and argon has a total pressure of 728 mmHg. The partial pressures of oxygen and argon are 234 mmHg and 135 mmHg respectively. What is the partial pressure of nitrogen?

At 24 °C and 745 mmHg, the density of an unknown gas is determined to be 7.76 g/L.What is the molar mass (g/mol) of this gas?

The pressure of a sample of argon gas was increased from 3.73 atm to 8.57 atm at constant temperature. If the final volume of the argon sample was 16.9 L, what was the initial volume of the argon sample? Assume ideal behavior.

A sample of nitrogen gas has a pressure of 70.5 mm Hg in a 610. mL flask. What is the pressure of this gas sample when it is transferred to a 129 mL flask at the same temperature?

A mixture of nitrogen and xenon gases is maintained in a 8.89 L flask at a temperature of 43°C. If the partial pressure of nitrogen is 0.426 atm and the partial pressure of xenon is 0.283 atm, the total pressure in the flask is atm.

4. A glass container was initially charged with 2.00 moles of a gas sample at 3.75 atm and 21.7 °C. Some of the gas was released as the temperature was increased to 28.1 °C, so the final pressure in the container was reduced to 0.998 atm. Assume the volume stayed the same. How many moles of the gas sample are present at the end?

A sample of argon gas has a volume of 735 mL at a pressure of 1.20 atm and a temperature of 112 °C. What is the final volume of the gas, in milliliters, when the pressure and temperature of the gas sample are changed to the following, if the amount of gas does not change? You may want to reference (Pages 272 - 273) Section 8.5 while completing this problem. Part C 17.0 atm and -22 °C Express your answer with the appropriate units. HA ? V = |10512.55 mL

A sample of chlorine gas with an initial volume of 35.6 L was found to have a volume of 27.2 L at 15.6 atm. What was the initial gas pressure (in atm)? Assume constant temperature. Do not include the actual units of measure in your answer.

A 8.350 L sample of gas is cooled from 81.50°C to a temperature at which its volume is 6.950 L. What is this new temperature? Assume no change in pressure of the gas.
