The number of mole of copper in the sample is 0.008 mole.
Mole is simply defined as the unit of amount in a substance.
The mole of a substance can be obtained by dividing the mass of the subtance by its molar mass i.e
Mole = mass / molar mass
With the above information, we can obtain the mole of copper in the compound as follow:
Mass of copper = 0.5066 g
Molar mass of copper = 63.5 g/mol
<h3>Mole of copper =? </h3>
Mole = mass / molar mass
Mole of copper = 0.5066 / 63.5
<h3>Mole of copper = 0.008 mole </h3>
Therefore, 0.008 mole of copper was initially present in the compound.
