Consider the combustion of carbon monoxide (CO) in oxygen gas:
$$2 \mathrm{CO}(g)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{CO}_{2}(g)$$Starting with 3.60 moles of $\mathrm{CO}$, calculate the number of moles of $\mathrm{CO}_{2}$ produced if there is enough oxygen gas to react with all of the CO.
