Computing Molar Mass of Pentadecene Step by Step
Molar Mass of Pentadecene: Step-by-Step Calculation
1. Identify Element Counts
Read C15H30 and list how many atoms of each element are present:
- 15 atoms of Carbon (C)
- 30 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): 15 x 12.011 = 180.160 g/mol
- Hydrogen (H): 30 x 1.008 = 30.240 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (15 x 12.011 + 30 x 1.008)
Molar Mass = 180.160 + 30.240
Molar Mass = 210.410 g/mol
Final rounded value shown on this page: 210.41 g/mol.
