The partial pressure of nitrogen at 1 atm is _____ mm Hg.
 
  a. 661.2 c. 159.6
  b. 592.8 d. 0.228

Question 2

The sum of the partial pressures of a gas mixture equals the total gas pressure of the system. This statement represents which of the following laws?
 
  a. Dalton's law
  b. Avogadro's law
  c. The combined-gas law
  d. Boltzmann's Universal Gas Constant

Answer to Question 1

ANS: B
The partial pressure of nitrogen can be calculated by multiplying the barometric pressure by the percentage of nitrogen in the air, or 760 mm Hg  0.78 = 592.8 mm Hg.

Answer to Question 2

ANS: A
The correct answer is Dalton's law. This law states that the total pressure of a gas is equal to the sum of the partial pressure of the gases that make up the mixture. The par-tial pressure of a gas within a gas mixture can be calculated by multiplying the total pressure of the mixture by the percentage of the mixture it occupies.
