Answer : The mass of copper produced will be, 11.796 grams
Explanation : Given,
Mass of
= 5 g
Molar mass of
= 26.98 g/mole
Molar mass of
= 63.66 g/mole
First we have to calculate the moles of
.
Now we have to calculate the moles of
.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of
react to give 3 moles of
So, 0.185 moles of
react to give
moles of
Now we have to calculate the mass of
.
The theoretical yield of Cu = 17.66 grams
Now we have to calculate the actual yield of Cu.

Now put all the given values in this formula, we get the actual yield of Cu.


Therefore, the mass of copper produced will be, 11.796 grams
