Hi CuSO4.10H2O (molar Mass)= 339.78g(1Cu+1S+14O+20H) mass of water in 339.78g ofCuSO4.10H2O =10x molar mass of water=10x18 =180g

Set up ratio

x/1000 = 180/339.78

X= 180x1000/339.78g

= 529.75 g

You can use percent method also .

percent of water in 339.78g= 180x100/339.78=52.975%

Now % of water in 1000g ofCuSO4.10H2O = 52.975%
