Molar and molecular weight of C12H22

• Relative molecular weight of C12H22: 166.30308
• Molar mass of C12H22: 166.30308 g/mol (0.1663 kg/mol)

Calculation of the relative molecular and molar mass of C12H22

• Mr[C12H22] = Ar[C] * 12 + Ar[H] * 22 = 12.0107 * 12 + 1.00794 * 22 = 166.30308
• Molar mass (kg/mol) = Mr[C12H22] : 1000 = 166.30308 : 1000 = 0.1663 kg/mol

C12H22: percent composition by element

• Carbon (C) = 144.1284 : 166.30308 * 100 = 86.666 %
