## Question:

Calculate the mole fraction of KCl in a solution that was prepared using 30 grams of KCl and 1.5 liters of water.

## Mole Fraction:

A solution concentration unit that is the ratio between the moles of solute and the total moles of solution is known as the mole fraction. The mole fraction is often represented by the symbol *X*. The sum of the mole fractions of the components of a mixture must sum to 1. For instance, a gaseous mixture of Ar and Ne must have a mole fraction that sum to 1. The expression for the mole fraction of Ar is:

{eq}\rm X_{Ar} = \dfrac{mol~Ar}{mol~Ar + mol~Ne } {/eq}
