Molar mass of Na2SO4 = 142 gm
Percent loss of water from Na2SO4 is 55
So,
![fraction numerator 18 straight n over denominator 142 plus 18 straight n end fraction cross times 100 space equals space 55 space](https://images.topperlearning.com/topper/tinymce/cache/70af9064e123e8abf4be554f3dba0b8a.png)
1800n = 7810 + 990n
n =9.64
n≈ 10 mol
