Computing Molar Mass of Nonanoic Acid Step by Step

Molar Mass of Nonanoic Acid: Step-by-Step Calculation

1. Identify Element Counts

Read C9H18O2 and list how many atoms of each element are present:

  1. 9 atoms of Carbon (C)
  2. 18 atoms of Hydrogen (H)
  3. 2 atoms 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): 9 x 12.011 = 108.100 g/mol
  • Hydrogen (H): 18 x 1.008 = 18.140 g/mol
  • Oxygen (O): 2 x 15.999 = 32.000 g/mol

4. Sum Total Molar Mass

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

Molar Mass = (9 x 12.011 + 18 x 1.008 + 2 x 15.999)

Molar Mass = 108.100 + 18.140 + 32.000

Molar Mass = 158.240 g/mol

Final rounded value shown on this page: 158.24 g/mol.
