Answer:-
6.4 moles
Explanation:-
The word 'Anhydrous' means no water of crystallization is present in the chemical formula.
The formula for anhydrous copper sulphate is CuSO4.
The word 'Hydrated' means water of crystallization is present in the chemical formula.
The formula for hydrated copper sulphate is CuSO4.5H2O
The balanced chemical equation for this reaction is
CuSO4.5H2O --> CuSO4 + 5 H2O
From the equation we can see that
1 mole of CuSO4.5H2O gives 1 mole of CuSO4
∴ 6.4 moles of CuSO4.5H2O gives 6.4 moles of CuSO4
