Computing Molar Mass of Nonadecanoic Acid Step by Step
Molar Mass of Nonadecanoic Acid: Step-by-Step Calculation
1. Identify Element Counts
Read C19H38O2 and list how many atoms of each element are present:
- 19 atoms of Carbon (C)
- 38 atoms of Hydrogen (H)
- 2 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Carbon (C) ~= 12.011 g/mol
- Hydrogen (H) ~= 1.008 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Carbon (C): 19 x 12.011 = 228.210 g/mol
- Hydrogen (H): 38 x 1.008 = 38.300 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 = (19 x 12.011 + 38 x 1.008 + 2 x 15.999)
Molar Mass = 228.210 + 38.300 + 32.000
Molar Mass = 298.510 g/mol
Final rounded value shown on this page: 298.51 g/mol.
