Chapter 7.8, Problem 1QQ

Interpretation Introduction

Interpretation:

Among the given options the correct one for statement “the partial pressure of helium gas in a gaseous mixture of helium and hydrogen” has to be chosen.

Concept Introduction:

Dalton’s law provides the information about partial pressures states of mixture of gases.  This law says that the total pressure exerted by a mixture of gases is the total sum of the partial pressures of the individual gases present in the mixture.  The mathematical expression for this law can be shown as follows,

${\text{P}}_{\text{Total}}\text{ = P1 + P2 + P3 +}\cdot \cdot \cdot$
