Molar and molecular weight of C2H5

• Relative molecular weight of C2H5: 29.0611
• Molar mass of C2H5: 29.0611 g/mol (0.02906 kg/mol)

Calculation of the relative molecular and molar mass of C2H5

• Mr[C2H5] = Ar[C] * 2 + Ar[H] * 5 = 12.0107 * 2 + 1.00794 * 5 = 29.0611
• Molar mass (kg/mol) = Mr[C2H5] : 1000 = 29.0611 : 1000 = 0.02906 kg/mol

C2H5: percent composition by element

• Carbon (C) = 24.0214 : 29.0611 * 100 = 82.658 %
• Hydrogen (H) = 5.0397 : 29.0611 * 100 = 17.342 %
