Molar and molecular weight of C18H27NO

• Relative molecular weight of C18H27NO: 273.41308
• Molar mass of C18H27NO: 273.41308 g/mol (0.27341 kg/mol)

Calculation of the relative molecular and molar mass of C18H27NO

• Mr[C18H27NO] = Ar[C] * 18 + Ar[H] * 27 + Ar[N] + Ar[O] = 12.0107 * 18 + 1.00794 * 27 + 14.0067 + 15.9994 = 273.41308
• Molar mass (kg/mol) = Mr[C18H27NO] : 1000 = 273.41308 : 1000 = 0.27341 kg/mol
