Molar and molecular weight of CH3CN

• Molecular formula: CH3CN or C2H3N
• Relative molecular weight of CH3CN: 41.05192
• Molar mass of CH3CN: 41.05192 g/mol (0.04105 kg/mol)

Calculation of the relative molecular and molar mass of CH3CN

• Mr[CH3CN] = Ar[C] * 2 + Ar[H] * 3 + Ar[N] = 12.0107 * 2 + 1.00794 * 3 + 14.0067 = 41.05192
• Molar mass (kg/mol) = Mr[CH3CN] : 1000 = 41.05192 : 1000 = 0.04105 kg/mol

CH3CN: percent composition by element

• Carbon (C) = 24.0214 : 41.05192 * 100 = 58.515 %
• Hydrogen (H) = 3.02382 : 41.05192 * 100 = 7.366 %
• Nitrogen (N) = 14.0067 : 41.05192 * 100 = 34.119 %
