Molar and molecular weight of Al(CH3)3

• Molecular formula: Al(CH3)3 or C3H9Al
• Relative molecular weight of Al(CH3)3: 72.0850986
• Molar mass of Al(CH3)3: 72.0850986 g/mol (0.07209 kg/mol)

Calculation of the relative molecular and molar mass of Al(CH3)3

• Mr[Al(CH3)3] = Ar[C] * 3 + Ar[H] * 9 + Ar[Al] = 12.0107 * 3 + 1.00794 * 9 + 26.9815386 = 72.0850986
• Molar mass (kg/mol) = Mr[Al(CH3)3] : 1000 = 72.0850986 : 1000 = 0.07209 kg/mol
