Computing Molar Mass of Eicosanol Step by Step
Molar Mass of Eicosanol: Step-by-Step Calculation
1. Identify Element Counts
Read C20H42O and list how many atoms of each element are present:
- 20 atoms of Carbon (C)
- 42 atoms of Hydrogen (H)
- 1 atom 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): 20 x 12.011 = 240.220 g/mol
- Hydrogen (H): 42 x 1.008 = 42.340 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 = (20 x 12.011 + 42 x 1.008 + 1 x 15.999)
Molar Mass = 240.220 + 42.340 + 16.000
Molar Mass = 298.560 g/mol
Final rounded value shown on this page: 298.56 g/mol.
