Answer 1

Well. first we need the balanced chemical equation, which will be:
CuSO4.5HOH = CUSO4 + 5HOH

Answer 2

So from the balanced equation we can look at the mole ration, 1 mol of hydrous salt produces 1 mole of anhydrous salt.

Answer 3

Since we know the mole ratio, is 1 to 1, we can solve for the rest of the equation.

Mol of hydrous salt= mass of hydrous salt/ mol mass of hydrous salt
= 2.3754/249.6= 0.00952
mol of anhydrous salt= 0.00952
mass of anhydrous salt =mol of salt x mol mass of anhydrous salt
= 0.00952 x 159.6 = 1.5194 g
