Molar and molecular weight of C5H7N

• Relative molecular weight of C5H7N: 81.11578
• Molar mass of C5H7N: 81.11578 g/mol (0.08112 kg/mol)

Calculation of the relative molecular and molar mass of C5H7N

• Mr[C5H7N] = Ar[C] * 5 + Ar[H] * 7 + Ar[N] = 12.0107 * 5 + 1.00794 * 7 + 14.0067 = 81.11578
• Molar mass (kg/mol) = Mr[C5H7N] : 1000 = 81.11578 : 1000 = 0.08112 kg/mol
