Mass
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.

Mass concentration (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.

Mass fraction (chemistry)
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.

Mixing ratio
In chemistry and physics, the dimensionless mixing ratio is the abundance of one component of a mixture relative to that of all other components.

Molar concentration
Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

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.
