Mole Fractions in Chemistry

Mole Fractions

• The mole fraction of a solvent is represented by the symbol 'X'.
• The mole fraction of a solvent can be visualized in a graph.
• The mole fraction of a solvent can be determined by looking at the figure.
• The mole fraction of a solvent can be expressed as a number between 0 and 1.

The 'X' Variable

• In chemistry, the mole fraction of a component is a measure of the amount of that component in a mixture.
• The mole fraction is defined as the moles of a component divided by the total moles of all components in the mixture.
• The mole fraction is a unitless quantity.
