Question

How many atoms are present in 4.00 mol of aluminum?

Answer 1

To determine the amount of atoms (or molecules) present given the moles of an element, you multiply the amount of moles by Avogadro's number, `6.022*10^23`

4 mol `Al` `(6.022*10^23)/(1 mol)`= `2.41*10^24` atoms/molecules of `Al`
