if yes then mark it as brainliest
Explanation:
The chemical formula of washing soda is Na
2 CO3 ⋅10H2O. It is sodium carbonate decahydrate. So it contains 10 water molecules.
as there is 1.698% of water crystallisation
then, no of. molecules = 10
no of molecules of water crystallisation per molecule == 168/100 * 10
== 16.8
