Molar and molecular weight of C6H6

• Relative molecular weight of C6H6: 78.11184
• Molar mass of C6H6: 78.11184 g/mol (0.07811 kg/mol)

Calculation of the relative molecular and molar mass of C6H6

• Mr[C6H6] = Ar[C] * 6 + Ar[H] * 6 = 12.0107 * 6 + 1.00794 * 6 = 78.11184
• Molar mass (kg/mol) = Mr[C6H6] : 1000 = 78.11184 : 1000 = 0.07811 kg/mol

C6H6: percent composition by element

• Carbon (C) = 72.0642 : 78.11184 * 100 = 92.258 %
• Hydrogen (H) = 6.04764 : 78.11184 * 100 = 7.742 %
