Computing Molar Mass of Decyne Step by Step
Molar Mass of Decyne: Step-by-Step Calculation
1. Identify Element Counts
Read C10H18 and list how many atoms of each element are present:
- 10 atoms of Carbon (C)
- 18 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): 10 x 12.011 = 120.110 g/mol
- Hydrogen (H): 18 x 1.008 = 18.140 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (10 x 12.011 + 18 x 1.008)
Molar Mass = 120.110 + 18.140
Molar Mass = 138.250 g/mol
Final rounded value shown on this page: 138.25 g/mol.
