Computing Molar Mass of Undecanol Step by Step

Molar Mass of Undecanol: Step-by-Step Calculation

1. Identify Element Counts

Read C11H24O and list how many atoms of each element are present:

  1. 11 atoms of Carbon (C)
  2. 24 atoms of Hydrogen (H)
  3. 1 atom of Oxygen (O)

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. Oxygen (O) ~= 15.999 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Carbon (C): 11 x 12.011 = 132.120 g/mol
  • Hydrogen (H): 24 x 1.008 = 24.190 g/mol
  • Oxygen (O): 1 x 15.999 = 16.000 g/mol

4. Sum Total Molar Mass

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

Molar Mass = (11 x 12.011 + 24 x 1.008 + 1 x 15.999)

Molar Mass = 132.120 + 24.190 + 16.000

Molar Mass = 172.310 g/mol

Final rounded value shown on this page: 172.31 g/mol.
