Answer:

To calculate the number of moles of copper, we first need to determine the mass of copper present in the sample:

Mass of copper = 159 g (mass of copper(II) oxide) - 127 g (mass of copper)

Mass of copper = 32 g

Now, we can use the molar mass of copper to calculate the number of moles:

Molar mass of copper = 63.55 g/mol

Number of moles of copper = mass of copper / molar mass of copper

Number of moles of copper = 32 g / 63.55 g/mol

Number of moles of copper = 0.504 mol

Therefore, there are 0.504 moles of copper in the sample.
