Answer – The molar mass of aluminum is 26.9815 g.
Explanation:
The molar mass of a substance (element or compound) is the mass of that substance in grams divided by its quantity in moles. Although its SI unit is kg/mol (kilograms per mole), it is often expressed in g/mol (grams per mole).
For any element, its atomic mass expressed in amu (atomic mass unit) is numerically equal to its mass per mole in grams. This means that an element’s atomic mass, which can be obtained from the periodic table, is numerically equal to its molar mass in grams per mole.
Since the atomic mass of aluminum is 26.9815 amu, its molar mass is simply equal to 26.9815 g/mol. This value represents the mass of 1 mole of aluminum, or 6.023 x 10²³ aluminum atoms.
Note: 1 mole = 6.023 x 10²³ particles, which can be atoms, molecules, ions, or other elementary particles
