Explanation: Oxygen has a molar mass of 16.00 g/mol. One mole of CO2 contains 32.00 grams of oxygen. One mole equals 22.4L at standard temperature and pressure.

## How many moles are in CO2?

we know the Molar mass of CO2 is 44. We also know the MM of carbon is 12 and the MM of oxygen is 16 (but there are two oxygens so its 32). So its just proportional really. Ok, so there are 0.114 moles of CO2.
