Molecular Mass of Carbon Dioxide
The Chemical Formula of Carbon Dioxide
The chemical formula of carbon dioxide is CO2, which signifies that one molecule of carbon dioxide consists of one carbon (C) atom and two oxygen (O) atoms.
Calculating the Molecular Mass of Carbon Dioxide
To calculate the mole mass of carbon dioxide, we need to consider the atomic masses of its constituent elements:
- Carbon (C) has an atomic mass of approximately 12.01 amu.
- Oxygen (O) has an atomic mass of approximately 16.00 amu.
Now, let’s calculate the mole mass of carbon dioxide:
mole Mass of Carbon Dioxide (CO2) = (1 x Atomic Mass of Carbon) + (2 x Atomic Mass of Oxygen) mole Mass of Carbon Dioxide = (1 x 12.01 amu) + (2 x 16.00 amu) mole Mass of Carbon Dioxide ≈ 44.01 amu
