  b. Multiplying the atmospheric pressure by the percentage of water vapor present
  c. Subtracting the partial pressure of water vapor from the atmospheric pressure

Answer to Question 1

ANS: C
Boltzmann's constant is represented as R. The combined-gas laws do not use the atomic mass or the partial pressure of any gas as a variable in any calculations presented in answers B and D.

Answer to Question 2

ANS: A
Dalton's law states that the sum of the partial pressures of a gas mixture equals the total pressure of the system. Therefore, the partial pressure of a single gas may be calculated by multiplying the percentage of the gas in the gas mixture by the total pressure.
