The question does not provide the equation
Answer:-
72.89 grams
Explanation:-
The balanced chemical equation for this reaction is
CuSO4 + Fe --> FeSO4 + Cu
Molecular weight of CuSO4 = 63.55 x 1 + 32 x 1 + 16 x 4
= 159.55 gram
Atomic weight of Cu = 63.55 gram.
According to the balanced chemical equation
1 CuSO4 gives 1 Cu
∴159.55 gram of CuSO4 would give 63.55 gram of Cu.
183 gram of CuSO4 would give 63.55 x 183 / 159.55
= 72.89 grams of Cu

During a chemical change the composition od the original substance is not altered and the change is irreversible. Melting of butter and wax is an example of chemical changes.</h3>
