<div>why is one molecule of plaster of paris having a share of only half a water molecule?</div>
Asked by SaiParvathi | 27 Aug, 2016, 07:14: PM
Expert Answer

Formula of plaster of Paris is CaSO4.1/2 H2O

It is not possible to have half a molecule of water.

The formula CaSO4.1/2 H2O over here actually means that two molecules of CaSO4 share one molecule of water.

The formula of plaster of Paris can also be written as 2CaSO4. H2O.
