Chapter 7, Problem 60P

Interpretation Introduction

Interpretation:

The balloon consists of gas O₂ with partial pressure 450mm Hg and the CO₂gas with partial pressure 150mm Hg. To this mixture, N₂ gas is added. The total pressure of balloon is 850mm Hg. The partial pressure of each gas in the final mixture needs to be determined.

Concept introduction:

According Dalton's law, the total pressure is the sum of the partial pressure of each gas. This can be represented as follows:

  ${\text{P}}_{\text{Total}}{\text{=P}}_{\text{molecule1}}{\text{+P}}_{\text{molecule2}}{\text{+P}}_{\text{molecule3}}$
