Molar and molecular weight of C2H5I

• Molecular formula: C2H5I or CH3CH2I
• Relative molecular weight of C2H5I: 155.96557
• Molar mass of C2H5I: 155.96557 g/mol (0.15597 kg/mol)

Calculation of the relative molecular and molar mass of C2H5I

• Mr[C2H5I] = Ar[C] * 2 + Ar[H] * 5 + Ar[I] = 12.0107 * 2 + 1.00794 * 5 + 126.90447 = 155.96557
• Molar mass (kg/mol) = Mr[C2H5I] : 1000 = 155.96557 : 1000 = 0.15597 kg/mol
