What is Al2O3’s Molar Mass?

Al₂O₃, also known as aluminum oxide, has a molar mass of 101.96 g/mol.

To calculate the molar mass of Al₂O₃, you need to consider the atomic masses of aluminum (Al) and oxygen (O). The atomic mass of aluminum is approximately 26.98 g/mol, and the atomic mass of oxygen is approximately 16.00 g/mol.

Since there are two aluminum atoms and three oxygen atoms in Al₂O₃, you can calculate the molar mass as follows:

Molar Mass of Al₂O₃ = (2 × 26.98 g/mol) + (3 × 16.00 g/mol)

Molar Mass of Al₂O₃ = 53.96 g/mol + 48.00 g/mol

Molar Mass of Al₂O₃ = 101.96 g/mol

Therefore, the molar mass of Al₂O₃ is 101.96 grams per mole.
