Which of the following factors determine how much of a given gas can dissolve in a liquid? 1. Solubility coefficient of the gas 2. Temperature of the liquid 3. Gas pressure above the liquid
 
  a. 2 and 3 only
  b. 1 and 2 only
  c. 1 and 3 only
  d. 1, 2, and 3

Question 2

In the lung's alveoli, there are four gases mixed together: O2, carbon dioxide, nitrogen, and water vapor.
 
  At a normal barometric pressure of 760 mm Hg, alveolar O2 exerts a partial pressure of 100 mm Hg, CO2 40 mm Hg, and water vapor 47 mm Hg. What is the alveolar partial pressure of nitro-gen?
  a. 187 mm Hg
  b. 713 mm Hg
  c. 660 mm Hg
  d. 573 mm Hg

Answer to Question 1

ANS: D
Henry's law predicts how much of a given gas will dissolve in a liquid. According to this princi-ple, at a given temperature, the volume of a gas that dissolves in a liquid is equal to its solubility coefficient times its partial pressure.

Answer to Question 2

ANS: D
Dalton's law describes the relationship among the partial pressure and the total pressure in a gas mixture. According to this law, the total pressure of a mixture of gases must equal the sum of the partial pressures of all component gases. Moreover, the principle states that the partial pressure of a component gas must be proportional to its percentage in the mixture.
