Molar and molecular weight of C5H5

• Relative molecular weight of C5H5: 65.0932
• Molar mass of C5H5: 65.0932 g/mol (0.06509 kg/mol)

Calculation of the relative molecular and molar mass of C5H5

• Mr[C5H5] = Ar[C] * 5 + Ar[H] * 5 = 12.0107 * 5 + 1.00794 * 5 = 65.0932
• Molar mass (kg/mol) = Mr[C5H5] : 1000 = 65.0932 : 1000 = 0.06509 kg/mol

C5H5: percent composition by element

• Carbon (C) = 60.0535 : 65.0932 * 100 = 92.258 %
• Hydrogen (H) = 5.0397 : 65.0932 * 100 = 7.742 %
