Sterling silver contains 92.5 wt% silver and 7.5 wt% copper. Copper is added to silver to make the metal stronger and more durable. A small sterling spoon has a mass of 100 g. Calculate the number of copper and silver atoms in the spoon. Note: need to find the mass of silver in the spoon, mass of copper in the spoon, number of mols of silver and copper, number of atoms assuming Avogadro's number of 6.02 x 1023 atoms per mol.
