Dimensionless quantities of chemistry

Dimensionless quantities in chemistry are values that do not have any units associated with them. These quantities arise when you normalize measurements or express them as ratios, allowing for comparison across different systems without the influence of the extensive physical dimensions. Some common examples of dimensionless quantities include: 1. **Mole Fraction**: The ratio of the number of moles of a component to the total number of moles in a mixture.

Mass fraction in chemistry refers to the ratio of the mass of a particular component of a mixture to the total mass of the mixture. It is a way to express the concentration of a component in a solution or a mixture.

Mole fraction is a way of expressing the concentration of a component in a mixture. It is defined as the ratio of the number of moles of one component to the total number of moles of all components in the mixture.
