How many molecules of carbon dioxide, CO₂, comprise 1.22 moles?
According to Avogadro's Number we have 6.02 * 10^23 molecules in one mol of molecules. So:
1 mol of CO₂ = 6.02 * 10^23 molecules of CO₂
Then:
1.22 moles of CO₂ * 6.02 * 10^23 molecules of CO₂ / 1 mol of CO₂ = 7.34 * 10^23 molecules of CO₂
There are 7.34 * 10^23 molecules of CO₂ in 1.22 moles of it
