# Mass concentration (chemistry) and Mass fraction (chemistry)

## Difference between Mass concentration (chemistry) and Mass fraction (chemistry)

### Mass concentration (chemistry) vs. Mass fraction (chemistry)

In chemistry, the mass concentration is defined as the mass of a constituent divided by the volume of the mixture: For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture. In chemistry, the mass fraction w_i is the ratio of one substance with mass m_i to the mass of the total mixture m_\text, defined as The symbol Y_i is also used to denote mass fraction.

## Similarities between Mass concentration (chemistry) and Mass fraction (chemistry)

Mass concentration (chemistry) and Mass fraction (chemistry) have 5 things in common (in Unionpedia): Chemistry, Density, Diffusion, Molar mass, Mole fraction.

### Chemistry

Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds.

### Density

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

### Diffusion

Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential) as a result of random motion of the molecules or atoms.

### Molar mass

In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance.

### Mole fraction

In chemistry, the mole fraction or molar fraction (xi) is defined as the amount of a constituent (expressed in moles), ni, divided by the total amount of all constituents in a mixture (also expressed in moles), ntot: The sum of all the mole fractions is equal to 1: The same concept expressed with a denominator of 100 is the mole percent or molar percentage or molar proportion (mol%).

### The list above answers the following questions

• What Mass concentration (chemistry) and Mass fraction (chemistry) have in common
• What are the similarities between Mass concentration (chemistry) and Mass fraction (chemistry)

## Mass concentration (chemistry) and Mass fraction (chemistry) Comparison

Mass concentration (chemistry) has 26 relations, while Mass fraction (chemistry) has 21. As they have in common 5, the Jaccard index is 10.64% = 5 / (26 + 21).
