Computing Molar Mass of Carbon Dioxide Step by Step
Molar Mass of Carbon Dioxide: Step-by-Step Calculation
1. Identify Element Counts
Read CO2 and list how many atoms of each element are present:
- 1 atom of Carbon (C)
- 2 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Carbon (C) ~= 12.011 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Carbon (C): 1 x 12.011 = 12.010 g/mol
- Oxygen (O): 2 x 15.999 = 32.000 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 12.011 + 2 x 15.999)
Molar Mass = 12.010 + 32.000
Molar Mass = 44.010 g/mol
Final rounded value shown on this page: 44.01 g/mol.
