Mass-specific quantities

In chemistry, molality is a measure of the amount of solute in a solution relative to a given mass of solvent. This contrasts with the definition of molarity which is based on a given volume of solution.

ratio of a substance's volume to its mass

total surface of a solid per mass

physical quantity representing energy content per unit mass

parameter in the gravitational two-body problem

quotient of the linear photon attenuation coefficient and the mass density
