Answer:

Explanation:

1mole of copper = 6.02 * 10^23 particles of copper

x mol of copper =2.2 * 10^23 particles

This is a proportion. All you need do is solve using the rules of proportions.

1/x = 6.02 * 10^23/2.2 * 10^23       Cross multiply

6.02 * 10^23x = 1* 2.2*10^23         Divide by 6.02 * 10^23

x = 2.2*10^23 / 6.02* 10^23

x = .365 mols of copper
