Molar and molecular weight of CH2

• Relative molecular weight of CH2: 14.02658
• Molar mass of CH2: 14.02658 g/mol (0.01403 kg/mol)

Calculation of the relative molecular and molar mass of CH2

• Mr[CH2] = Ar[C] + Ar[H] * 2 = 12.0107 + 1.00794 * 2 = 14.02658
• Molar mass (kg/mol) = Mr[CH2] : 1000 = 14.02658 : 1000 = 0.01403 kg/mol

CH2: percent composition by element

• Carbon (C) = 12.0107 : 14.02658 * 100 = 85.628 %
• Hydrogen (H) = 2.01588 : 14.02658 * 100 = 14.372 %
