One mole of copper has a mass of 63.5 grams. approximately how many atoms of copper are present in one mole of copper?

atoms

Explanation: According to the mole concept give by Avogadro, 1 mole of every compound contains same number of atoms, molecules or ions.

Thus 1 mole of Copper atom contains atoms.

And 1 mole of every substance weighs equal to the molecular mass of that substance. Thus atoms weigh equal to 63.5 g.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
