In materials science and metallurgy, Vegard’s law is the empirical heuristic that the lattice parameter of a solid solution of two constituents is
The density of a material is defined as its mass per unit volume. For a pure substance the density has the same numerical value as its mass concentration.
An activity coefficient is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances.In an ideal
Amount of Substance
Amount of substance (n) is the number of atoms, molecules, ions, or other specified group of entities present in a compound. It is the ratio of Mass /
In a mixture, the mass fraction is the amount of mass of one substance, divided by the mass of the total mixture. The sum of all the mass fractions is
In physics, Henry’s law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
