Computing Molar Mass of Chloroethane Step by Step

Molar Mass of Chloroethane: Step-by-Step Calculation

1. Identify Element Counts

Read C2H5Cl and list how many atoms of each element are present:

  1. 2 atoms of Carbon (C)
  2. 5 atoms of Hydrogen (H)
  3. 1 atom of Chlorine (Cl)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Carbon (C) ~= 12.011 g/mol
  2. Hydrogen (H) ~= 1.008 g/mol
  3. Chlorine (Cl) ~= 35.450 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Carbon (C): 2 x 12.011 = 24.020 g/mol
  • Hydrogen (H): 5 x 1.008 = 5.040 g/mol
  • Chlorine (Cl): 1 x 35.450 = 35.450 g/mol

4. Sum Total Molar Mass

Add all contributions to get the final molar mass in g/mol.

Molar Mass = (2 x 12.011 + 5 x 1.008 + 1 x 35.450)

Molar Mass = 24.020 + 5.040 + 35.450

Molar Mass = 64.510 g/mol

Final rounded value shown on this page: 64.51 g/mol.
