Computing Molar Mass of Chlorooctadecane Step by Step

Molar Mass of Chlorooctadecane: Step-by-Step Calculation

1. Identify Element Counts

Read C18H37Cl and list how many atoms of each element are present:

  1. 18 atoms of Carbon (C)
  2. 37 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): 18 x 12.011 = 216.200 g/mol
  • Hydrogen (H): 37 x 1.008 = 37.300 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 = (18 x 12.011 + 37 x 1.008 + 1 x 35.450)

Molar Mass = 216.200 + 37.300 + 35.450

Molar Mass = 288.940 g/mol

Final rounded value shown on this page: 288.94 g/mol.
