Chapter 4, Problem 61E
Interpretation Introduction
Interpretation:
The final pressure of the gas brought about by the change in temperature is to be calculated.
Concept introduction:
According to Amonton's law, the pressure and absolute temperature of a gas are directly proportional to each other under the conditions of constant volume. Mathematically, under two different conditions of pressure and temperature:
The temperature in Celsius and Kelvin scale can be related as:

Air is approximately 78% nitrogen, 21% oxygen, and 1% argon (note that unless stated explicitly, gas concentrations are always expressed in terms of partial pressures (or mole fractions), so a gas "concentration" of 78% implies 78% of the total pressure is due to that gas). That average volume of breath a healthy adult woman takes is 400. mL. If a woman breathes in air at 22.0 C with a total barometric pressure of 0.97 atm and it warms to her core temperature of 37.6 C, what is the partial pressure of the three components of air in her lungs? (Assume that the volume of the gas does not change as the gas warms up.)
Two bulbs are connected by a stopcock. The large bulb, with a volume of 6.00 L, contains nitric oxide at a pressure of 41.5 kPa41.5 kPa, and the small bulb, with a volume of 1.50 L, contains oxygen at a pressure of 250 kPa. The temperature at the beginning and the end of the experiment is 22 °C.
After the stopcock is opened, the gases mix and react to form nitrogen dioxide.
2NO(g)+O2(g)⟶2NO2(g)2NO(g)+O2(g)⟶2NO2(g)
Which gases are present at the end of the reaction?
NO
O2
NO2
Calculate the partial pressures of the gases. If the gas was consumed completely, put 0 for the answer.
11. (a) In a 20.0 L steel container, we have only 77.7 g of CO2(g), 66.6 g of N2(g), and O2(g).
The temperature is 25.0 ◦C and the total pressure is 8.88 atm. What mass of O2(g) do we have, and
what is its partial pressure? The molar masses of C, N, and O are 12.01, 14.01, and 16.00 g/mol.
(b) The density of a sample of pure CH4(g) at a constant pressure of 1.00 atm is 0.666 g/L.
What is the average speed, or root mean square speed, of the CH4(g) molecules in this sample? The
molar masses of C and H are 12.01 and 1.01 g/mol.
