Understand that the molar mass of an element is the mass of one mole of its atoms, usually expressed in grams per mole (g/mol).
Locate aluminum (Al) on the periodic table to find its atomic mass, which is numerically equal to its molar mass in g/mol.
Identify the atomic mass of aluminum, which is typically found as a decimal number near the element symbol on the periodic table.
Recognize that the molar mass of aluminum corresponds to this atomic mass value, representing the mass of one mole of aluminum atoms.
Conclude that the molar mass of aluminum is the atomic mass value you found, expressed in g/mol.
