Water is sprayed into air at $80^{\circ} \mathrm{F}$ and 14.3 psia, and the falling water droplets are collected in a container on the floor. Determine the mass and mole fractions of air dissolved in the water.

Key Concepts

Henry's Law

Henry's Law states that the concentration of a gas dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid. This concept is crucial when determining the solubility of gases in a liquid under varying conditions of temperature and pressure, as it provides the equilibrium condition between the gas phase and the dissolved gas in the liquid.

Partial Pressure

Partial pressure refers to the pressure exerted by an individual gas component in a mixture of gases. In the context of gas solubility, it is the partial pressure of the component gas (or mixture of gases) in contact with the liquid that determines how much of that gas dissolves, as described by Henry's Law.

Gas Solubility in Liquids

Gas solubility in liquids is the measure of how much gas can be dissolved in a liquid at a given temperature and pressure. This concept involves understanding that solubility varies with temperature and pressure and that equilibrium conditions must be established between the gas and liquid phases for accurate determination of dissolved concentrations.

Mole and Mass Fractions

Mole and mass fractions are measures of composition in mixtures. The mole fraction represents the ratio of the number of moles of a component to the total number of moles, while the mass fraction represents the ratio of the mass of a component to the total mass. Converting between these fractions is essential when analyzing the composition of a mixture or solution, such as determining the amount of dissolved gas relative to the solvent.
