Text solutionVerified

The concentration of solid or liquid is

\frac{Number of moles}{volume in L}

= \frac{Mass}{Volume \times molar mass}

= \frac{Density}{Molar mass}

.
At constant temperature, the density and molar mass of pure solid and liquid are constant.
Due to this, their molar concentrations are constant and are not included in the equilibrium constant.
