Computing Molar Mass of Chloroheptane Step by Step
Molar Mass of Chloroheptane: Step-by-Step Calculation
1. Identify Element Counts
Read C7H15Cl and list how many atoms of each element are present:
- 7 atoms of Carbon (C)
- 15 atoms of Hydrogen (H)
- 1 atom of Chlorine (Cl)
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
- Chlorine (Cl) ~= 35.450 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): 15 x 1.008 = 15.120 g/mol
- Chlorine (Cl): 1 x 35.450 = 35.450 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 + 15 x 1.008 + 1 x 35.450)
Molar Mass = 84.080 + 15.120 + 35.450
Molar Mass = 134.650 g/mol
Final rounded value shown on this page: 134.65 g/mol.
