Chapter 6, Problem 6.107QP

Interpretation Introduction

Interpretation: The excess ${\text{O}}_{\text{2}}$ present in the lung full of pure ${\text{O}}_{\text{2}}$ at $\text{8000}\text{m}$ peak than in the lung full of air at sea level is to be calculated.

Concept introduction: At higher altitudes, the oxygen percentage is very low as the air gets thinner when we are going above the sea level. So, mountain climbers use pure oxygen to climb at higher altitudes near $\text{8000}\text{m}$ peaks by filling their oxygen cylinder. Mole fraction is defined by the fraction between the number of moles of the given substance by the total number of moles in the gas mixture.

To Calculate: The excess ${\text{O}}_{\text{2}}$ present in the lung full of pure ${\text{O}}_{\text{2}}$ at $\text{8000}\text{m}$ peak than in the lung full of air at sea level.
