We use #"Avogadro's number"# to give the number of aluminum atoms.

Explanation:

One mole of stuff specifies #N_A, "Avogadro's number, "# #6.02214xx10^23*mol^-1# individual particles.

We have #4.25*mol#, i.e. #4.25*cancel(mol)xx6.02214xx10^23*cancel(mol^-1)# #"aluminum atoms"#, approx. #25xx10^23# #"aluminum atoms"#. What is the mass of this number of atoms?
