Computing Molar Mass of Propane Step by Step
Molar Mass of Propane: Step-by-Step Calculation
1. Identify Element Counts
Read C3H8 and list how many atoms of each element are present:
- 3 atoms of Carbon (C)
- 8 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): 3 x 12.011 = 36.030 g/mol
- Hydrogen (H): 8 x 1.008 = 8.060 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (3 x 12.011 + 8 x 1.008)
Molar Mass = 36.030 + 8.060
Molar Mass = 44.100 g/mol
Final rounded value shown on this page: 44.10 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Carbon (C) | 3 | 12.011 | 3 x 12.011 | = 36.030 |
| Hydrogen (H) | 8 | 1.008 | 8 x 1.008 | = 8.060 |
Final molar mass 36.030 + 8.060 | = 44.100 | |||
