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.
