What is mole fraction?
Understand the Problem
The question is asking for the definition or explanation of mole fraction, which is a concept in chemistry that refers to the ratio of the amount of a particular substance to the total amount of all substances in a mixture. This is an important concept in the study of solutions and mixtures in chemistry.
Answer
The mole fraction is the ratio of moles of one component to the total moles in a mixture.
The mole fraction is a ratio of the moles of one component in a mixture to the total moles of all components.
Answer for screen readers
The mole fraction is a ratio of the moles of one component in a mixture to the total moles of all components.
More Information
Mole fraction is a useful way to express the concentration of a component in a mixture and is dimensionless. It is particularly useful in situations involving partial pressures in gases.
Tips
A common mistake is confusing mole fraction with molarity, which involves volume.
