how many moles of oxygen gas are necessary to form 0.737 moles of carbon dioxide
CO2 has just as many O atoms as O2
so the same number of mols
To determine the number of moles of oxygen gas needed to form 0.737 moles of carbon dioxide, you should consider the balanced chemical equation for the reaction that produces carbon dioxide from oxygen gas.
The balanced equation for the combustion of carbon in oxygen to form carbon dioxide is:
C + O2 -> CO2
From the equation, we can see that one mole of carbon reacts with one mole of oxygen gas to produce one mole of carbon dioxide.
So, we can conclude that 0.737 moles of carbon dioxide will require the same number of moles of oxygen gas. Therefore, 0.737 moles of oxygen gas are necessary to form 0.737 moles of carbon dioxide.
