Molar and molecular weight of C2H6O

• Molecular formula: C2H6O or C2H5OH
• Relative molecular weight of C2H6O: 46.06844
• Molar mass of C2H6O: 46.06844 g/mol (0.04607 kg/mol)

Calculation of the relative molecular and molar mass of C2H6O

• Mr[C2H6O] = Ar[C] * 2 + Ar[H] * 6 + Ar[O] = 12.0107 * 2 + 1.00794 * 6 + 15.9994 = 46.06844
• Molar mass (kg/mol) = Mr[C2H6O] : 1000 = 46.06844 : 1000 = 0.04607 kg/mol
