Molar and molecular weight of TaI5

• Molecular formula: TaI5 or I5Ta
• Relative molecular weight of TaI5: 815.47025
• Molar mass of TaI5: 815.47025 g/mol (0.81547 kg/mol)

Calculation of the relative molecular and molar mass of TaI5

• Mr[TaI5] = Ar[I] * 5 + Ar[Ta] = 126.90447 * 5 + 180.9479 = 815.47025
• Molar mass (kg/mol) = Mr[TaI5] : 1000 = 815.47025 : 1000 = 0.81547 kg/mol

TaI5: percent composition by element

• Iodine (I) = 634.52235 : 815.47025 * 100 = 77.811 %
• Tantalum (Ta) = 180.9479 : 815.47025 * 100 = 22.189 %
