Chapter 14, Problem 108IAE

Interpretation Introduction

Interpretation:

The mass of Ar in a liter of ocean water and the partial pressure of Ar in the atmosphere should be calculated.

Concept introduction:

The concentration of a solution is related to number of moles of solute and volume of solution as follows:

$\begin{array}{l}\text{Concentartion = }\frac{\text{Number of Solute moles }}{\text{Volume of the solution }}\\ \text{}{\text{C = K}}_H\times {\text{P}}_{gas}\\ \text{C = solubility of gas}\\ {\text{K}}_H=\text{ Henry's law constant}\\ {\text{P}}_{gas}\text{ = partial pressure of the the gas above the solution}\\ \\ \text{Partial pressure of a gas = Total pressure }\times \text{ mole fraction of the gas}\\ \end{array}$
