A mole fraction is what?

the proportion of the moles of one component to the total moles of all the components in a solution or other mixture.

What is mole fraction and an example of it?

The ratio of molecules of one component in a mixture is known as a mole fraction. For instance, if the methane mole fraction in a gas is 0.90, then this implies that 90% of the molecules are methane. The mixture also contains 90% methane since the amount fractions resemble mole fractions.

How is the mole fraction determined?

By dividing the moles of the solute by the total moles of the substances in the solution, you may determine the mole fraction of the solute.
