Answer : The theoretical yield of copper is, 79.375 grams
Explanation : Given,
Mass of copper(II) sulfate = 200 g
Molar mass of copper(II) sulfate = 159.6 g/mole
Molar mass of copper = 63.5 g/mole
First we have to calculate the moles of
.
![\text{Moles of }CuSO_4=\frac{\text{Mass of }CuSO_4}{\text{Molar mass of }CuSO_4}=(200g)/(159.6g/mole)=1.25moles](https://img.qammunity.org/2019/formulas/chemistry/college/5eagapbqc3fcx1ukrfz4ws5reqca0667qc.png)
Now we have to calculate the moles of copper.
The balanced chemical reaction will be :
![CuSO_4+Zn\rightarrow ZnSO_4+Cu](https://img.qammunity.org/2019/formulas/chemistry/college/583l9kk9wkhhouy9m090lqnl2xc4g4l9yx.png)
From the balanced chemical reaction, we conclude that
As, 1 mole of
react to give 1 mole of
So, 1.25 moles of
react to give 1.25 moles of
Now we have to calculate the mass of Cu.
![\text{Mass of }Cu=(1.25mole)* (63.5g/mole)=79.375g](https://img.qammunity.org/2019/formulas/chemistry/college/ad5kr9mwknvouvmux5ty3qy6ulx7nqn7it.png)
Therefore, the theoretical yield of copper is, 79.375 grams
