Computing Molar Mass of Styrene Step by Step
Molar Mass of Styrene: Step-by-Step Calculation
1. Identify Element Counts
Read C8H8 and list how many atoms of each element are present:
- 8 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): 8 x 12.011 = 96.090 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 = (8 x 12.011 + 8 x 1.008)
Molar Mass = 96.090 + 8.060
Molar Mass = 104.150 g/mol
Final rounded value shown on this page: 104.15 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Carbon (C) | 8 | 12.011 | 8 x 12.011 | = 96.090 |
| Hydrogen (H) | 8 | 1.008 | 8 x 1.008 | = 8.060 |
Final molar mass 96.090 + 8.060 | = 104.150 | |||
