Molecular Formula of calcium sulphate is CaSO4.
the molecular weight of water =
atomicmass of Ca + atomic mass of s+4xatomic mass of oxygen
=40 + 32 + 4x16
136 amu
the gram molecular weight of CaSO4 is 136g
According to mole concept :
One mole of CasO4 contains 6.023 x10 power 23 molecules of Caso4, is equivalent to 1 gram molecule of Caso4 and weighs 136g.
