# For a mass of 1*g with respect to hydrogen atoms, and a mass of 63.5*g with respect to copper atoms, how do the numbers of each sets atoms compare?

There are the same number of atoms in each sample.

#### Explanation:

It is a fact that if there is a mass of approximately 1.01 g of hydrogen atoms, there are Avogadro's number of hydrogen ATOMS. It is also a fact that Avogadro's number of copper atoms have a mass of 63.55 g. Both quantities represent a mole of stuff. This is a very important result to get your head around.
