Molar and molecular weight of BaI2

• Relative molecular weight of BaI2: 391.13594
• Molar mass of BaI2: 391.13594 g/mol (0.39114 kg/mol)

Calculation of the relative molecular and molar mass of BaI2

• Mr[BaI2] = Ar[Ba] + Ar[I] * 2 = 137.327 + 126.90447 * 2 = 391.13594
• Molar mass (kg/mol) = Mr[BaI2] : 1000 = 391.13594 : 1000 = 0.39114 kg/mol

BaI2: percent composition by element

• Barium (Ba) = 137.327 : 391.13594 * 100 = 35.11 %
• Iodine (I) = 253.80894 : 391.13594 * 100 = 64.89 %
