Computing Molar Mass of Heptadecane Step by Step
Molar Mass of Heptadecane: Step-by-Step Calculation
1. Identify Element Counts
Read C17H36 and list how many atoms of each element are present:
- 17 atoms of Carbon (C)
- 36 atoms of Hydrogen (H)
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
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Carbon (C): 17 x 12.011 = 204.190 g/mol
- Hydrogen (H): 36 x 1.008 = 36.290 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (17 x 12.011 + 36 x 1.008)
Molar Mass = 204.190 + 36.290
Molar Mass = 240.470 g/mol
Final rounded value shown on this page: 240.47 g/mol.
