Specific volume is defined as the amount of [[Volume|volume]] occupied by a [[Substance|substance]] per unit [[Mass|mass]]: $\nu=\dfrac{V}{m}$ Where $\nu$ is specific volume, $V$ is volume, and $m$ is mass. Density ($\rho$) is defined as the amount of mass of a substance per unit volume it occupies: $\rho=\dfrac{m}{V}$ Specific volume and density are the reciprocal of one another: $\nu=\dfrac{1}{\rho}$
