Molar and molecular weight of YbI2

• Molecular formula: YbI2 or I2Yb
• Relative molecular weight of YbI2: 426.84894
• Molar mass of YbI2: 426.84894 g/mol (0.42685 kg/mol)

Calculation of the relative molecular and molar mass of YbI2

• Mr[YbI2] = Ar[I] * 2 + Ar[Yb] = 126.90447 * 2 + 173.04 = 426.84894
• Molar mass (kg/mol) = Mr[YbI2] : 1000 = 426.84894 : 1000 = 0.42685 kg/mol

YbI2: percent composition by element

• Iodine (I) = 253.80894 : 426.84894 * 100 = 59.461 %
• Ytterbium (Yb) = 173.04 : 426.84894 * 100 = 40.539 %
