Answer:
77.98 g/mol ≅ 78.0 g/mol.
Explanation:
- The molar mass of any compound can be calculated by the sum of the atomic masses of different atoms in the compound multiplied by its no. in the compound.
Molar mass of Al(OH)₃ = (Atomic mass of Al) + 3(Atomic mass of O) + 3(Atomic mass of H)
Atomic mass of Al = 26.98 g/mol. & Atomic mass of O = 16.0 g/mol & Atomic mass of H = 1.0 g/mol.
<em>∴ Molar mass of Al(OH)₃</em> = (26.98 g/mol) + 3(16.0 g/mol) + 3(1.0 g/mol) = <em>77.98 g/mol ≅ 78.0 g/mol.</em>
