Explain how the mass of a single atom in an element (in amu), the mass of one mole of that element, and Avogadro's number are related.

Answer: For 1 mole of a single atom it is equal to its molar mass. And a single atom, 1 mole is equal to the Avogadro's Number.

Explanation: The relationship can be expressed through the following:

1 mole = molar mass of an atom / compound

1 atom x 1 mole / 6.022x10^23 atoms
