Molar mass of carbon dioxide (CO2)

The molar mass of carbon dioxide (CO2) is 44.009 g/mol.

Step-by-step calculation

Element	Atoms	Atomic mass	Subtotal
Carbon	× 1	12.011	= 12.011
Oxygen	× 2	15.999	= 31.998
Total			44.009 g/mol

Carbon dioxide is a colorless, odorless gas made of one carbon atom double-bonded to two oxygen atoms.
It is released by breathing, burning fuels, and fermentation, and it is absorbed by plants during photosynthesis and used to carbonate soft drinks.
At normal atmospheric pressure, solid carbon dioxide, known as dry ice, turns directly into a gas at about -78.5 °C without melting.

What is the molar mass of CO2?

The molar mass of carbon dioxide (CO2) is 44.009 g/mol.

How do you calculate the molar mass of CO2?

Multiply the atomic mass of each element by the number of its atoms in CO2, then add the results: 1 × 12.011 (C) + 2 × 15.999 (O) = 44.009 g/mol.

What percentage of CO2 is Oxygen?

Oxygen makes up 72.71% of the mass of carbon dioxide (CO2).
