A given mass of a gas occupies 5.00 L at 65 °C and 480
mmHg. What is the volume of the gas at 630 mmHg and
85 °C? - ANS ✓c. 5.00 ×358/338×480/630
Consider the reaction below, in which 6 atm of
ammonium nitrite is added to an evacuated flask with a
catalyst and then heated.

partial pressure of the water vapor at equilibrium - ANS ✓d. 8.0 atm
A 5.0 L sample of gas is collected at 400. mmHg at
727ºC. What is the volume if the temperature were cooled
to 77ºC and the pressure increased to 700. mmHg? - ANS ✓e. 1.0 L

helium with a partial pressure of 1500 mmHg. The
remaining gas is hydrogen, what is the mass of hydrogen
in the flask? - ANS ✓c. 4.0 g
The temperature of a sample of an ideal gas confined in a
2.0 L container was raised from 27ºC to 77ºC. If the initial
pressure of the gas was 1,200 mmHg, what was the final
pressure of the gas? - ANS ✓b. 1,400 mmHg
A sealed container containing 8.0 grams of oxygen gas
and 7.0 g of nitrogen gas is kept at a constant temperature
and pressure. Which of the following is true? - ANS ✓b. The volume occupied
by oxygen is equal to the
volume occupied by nitrogen.
A gas sample contains 0.1 mole of oxygen and 0.4 mole
of nitrogen. If the sample is at standard temperature and
pressure, what is the partial pressure due to nitrogen? - ANS ✓d. 0.8 atm
A mixture of gases contains 1.5 moles of oxygen, 3.0
moles of nitrogen, and 0.5 mole of water vapor. If the
total pressure is 700 mmHg, what is the partial pressure of
the nitrogen gas? - ANS ✓e. 420 mmHg
