Let the water of hydration be x.
Now mass of water=6 - 4.4=1.6g.
Moles of salt in LHS= 6/150
Therefore,moles of water in =6x/150
Mass of water=(6x/150)18
And in reaction we have find that mass of water is 1.6g(...in 2nd line..)
Therefore,(6x/150)18=1.6g
                x=2.2222..
So,water of hydration is 2

 M xH2O ----------->      M     +    xH2O              
(150+8x/6)                (150/4.4)                    ,
therefore, on cross multipling ,  [ (150 + 18x)4.4  =  150 × 6 ]
