उत्तर
The chemical formula of plaster of Paris is \[\ce{\underline{\mathbf{CaSO_4.\frac{1}{2}H_2O}}}\].
Explanation:
Plaster of Paris is obtained by heating gypsum (CaSO4.2H2O) carefully to a specific temperature of 373 K. At this temperature, the gypsum loses three-fourths of its water of crystallisation to form a white powder. When mixed back with water, it rehydrates and sets quickly into a hard, solid mass of gypsum.
