If a student calculated 0.03256 moles of copper metal (cu0), how many grams of copper metal (cu0) should be recovered at the end of the experiment?

Mass of copper metal will be 2.06756 gram

Explanation:

We have given number of moles of copper n = 0.03256

Molar mass of copper = 63.5 u

We have to calculate mass of copper metals in gram

We know that number of moles is given by

Mass in gram = 2.06756 gram

So mass of copper metal will be 2.06756 gram

the answer is b & c i believe : )
