The chemical formula of plaster of Paris is 2CaSO4.H2O
Explanation:
Plaster of Paris, shortly known by the acronym POP, contains two molecules of CaSO4 with each water molecule. It is made by calcining gypsum and mainly used for casts and molds as it is a quick-setting white paste when mixed with water. You can find it as the hard white substance that is applied when one has a broken bone. It is also used on walls, ceilings and other structures to obtain a smooth hard surface.
