What is the molar mass of al(oh)^3? report your answer top the nearest 0.1 g/mol

77.98 g/mol ≅ 78.0 g/mol.

Explanation:

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.

∴ Molar mass of Al(OH)₃ = (26.98 g/mol) + 3(16.0 g/mol) + 3(1.0 g/mol) = 77.98 g/mol ≅ 78.0 g/mol.
