Molar and molecular weight of CH2I2

• Relative molecular weight of CH2I2: 267.83552
• Molar mass of CH2I2: 267.83552 g/mol (0.26784 kg/mol)

Calculation of the relative molecular and molar mass of CH2I2

• Mr[CH2I2] = Ar[C] + Ar[H] * 2 + Ar[I] * 2 = 12.0107 + 1.00794 * 2 + 126.90447 * 2 = 267.83552
• Molar mass (kg/mol) = Mr[CH2I2] : 1000 = 267.83552 : 1000 = 0.26784 kg/mol

CH2I2: percent composition by element

• Carbon (C) = 12.0107 : 267.83552 * 100 = 4.484 %
• Hydrogen (H) = 2.01588 : 267.83552 * 100 = 0.753 %
• Iodine (I) = 253.80894 : 267.83552 * 100 = 94.763 %
