(B) Lyophilic sols are stabilized by adding lyophilic colloids,which protect them from precipitation. These are called protecting colloids.Their protecting power is expressed in terms of $gold \ number$.$Gold \ number$ is defined as the minimum amount of lyophilic colloid in milligrams that prevents the flocculation of $10 \ mL$ of gold sol by the addition of $1 \ mL$ of $10 \ \% \ NaCl$ solution.Lesser the $gold \ number$,higher is the protecting power.

The protecting power of lyophilic colloidal sol is expressed in terms of
