the chemical formula of POP is CaSO4.1/2H2O, How can H2O be (1/2) divided
Hi!
@Rane
Plaster of Paris has the actual formula 2CaSO4.H2O. For every 2 molecules of calcium sulphate, one molecule of water is present. CaSO4.1/2H2O is just a simplified way of writing.
@Anubhav
Hey, you got it correct. But I guess in haste you missed out the water of crystallisation present along with 2CaSO4 in POP.
But, this is a great answer. Keep it up!
@Rahul
Good attempt!
The lines you wrote down are correct but it is not the exact answer to the question made by Rane.
So, let me make this clear for you.
