Molar and molecular weight of C2H7N

• Molecular formula: C2H7N or CH3CH2NH2
• Relative molecular weight of C2H7N: 45.08368
• Molar mass of C2H7N: 45.08368 g/mol (0.04508 kg/mol)

Calculation of the relative molecular and molar mass of C2H7N

• Mr[C2H7N] = Ar[C] * 2 + Ar[H] * 7 + Ar[N] = 12.0107 * 2 + 1.00794 * 7 + 14.0067 = 45.08368
• Molar mass (kg/mol) = Mr[C2H7N] : 1000 = 45.08368 : 1000 = 0.04508 kg/mol
