To calculate the number of moles of copper produced in the experiment, we need to use the formula:
moles = mass / molar mass
The molar mass of copper is 63.55 g/mol.
Substituting the values:
moles = 1.27 g / 63.55 g/mol
moles = 0.02 mol
Therefore, 0.02 moles of copper were produced in the experiment.
