Computing Molar Mass of Hexadecane Step by Step
Molar Mass of Hexadecane: Step-by-Step Calculation
1. Identify Element Counts
Read C16H34 and list how many atoms of each element are present:
- 16 atoms of Carbon (C)
- 34 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): 16 x 12.011 = 192.180 g/mol
- Hydrogen (H): 34 x 1.008 = 34.270 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (16 x 12.011 + 34 x 1.008)
Molar Mass = 192.180 + 34.270
Molar Mass = 226.450 g/mol
Final rounded value shown on this page: 226.45 g/mol.
