Answer:

Explanation:

Aluminum has an atomic molar mass of 27 grams per mole.

Al has 13 protons (hence number 13) and it most common isotope 14 neutrons for a total mass of 27 amu. ( The 13 electrons add no measurable mass to the atom )

Take the grams and divide by the molar mass

54/1 / 27/1 = 54/27

= 2 moles
