Computing Molar Mass of Octyne Step by Step
Molar Mass of Octyne: Step-by-Step Calculation
1. Identify Element Counts
Read C8H14 and list how many atoms of each element are present:
- 8 atoms of Carbon (C)
- 14 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): 14 x 1.008 = 14.110 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 + 14 x 1.008)
Molar Mass = 96.090 + 14.110
Molar Mass = 110.200 g/mol
Final rounded value shown on this page: 110.20 g/mol.
