Mass fraction (relation between mass and molar concentration)
Description
In chemistry, the mass concentration is defined as the mass of a constituent divided by the volume of the mixture. The mass concentration of a component in a mixture can be called the density of a component in a mixture. Molar concentration is defined as the amount of a constituent (usually measured in moles ) divided by the volume of the mixture. There is a relation between mass and molar concentration, using the molar mass of the component.
