Molar and molecular weight of C6H4O2

• Relative molecular weight of C6H4O2: 108.09476
• Molar mass of C6H4O2: 108.09476 g/mol (0.10809 kg/mol)

Calculation of the relative molecular and molar mass of C6H4O2

• Mr[C6H4O2] = Ar[C] * 6 + Ar[H] * 4 + Ar[O] * 2 = 12.0107 * 6 + 1.00794 * 4 + 15.9994 * 2 = 108.09476
• Molar mass (kg/mol) = Mr[C6H4O2] : 1000 = 108.09476 : 1000 = 0.10809 kg/mol
