Computing Molar Mass of Toluene Step by Step
Molar Mass of Toluene: Step-by-Step Calculation
1. Identify Element Counts
Read C7H8 and list how many atoms of each element are present:
- 7 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): 7 x 12.011 = 84.080 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 = (7 x 12.011 + 8 x 1.008)
Molar Mass = 84.080 + 8.060
Molar Mass = 92.140 g/mol
Final rounded value shown on this page: 92.14 g/mol.
