Oxygen molecules contain two oxygen atoms, and carbon dioxide molecules contain one atom of carbon and two atoms of oxygen. How does the total number of molecules in 1 liter of oxygen compare with the total number of atoms in 1 liter of carbon dioxide if they are both at the same tempature and pressure?

Question

Thank you.

Answer 1

total number of atoms: 3*avagradrosnumber
total number of O2 molecules: avagradnumber

this is for one volume, 1/22.4 mole of each CO2 and O2
