Question

Consider the combustion of carbon monoxide (CO) in oxygen gas:

2CO(g) + O2(g) → 2CO2(g)

Starting with 4.43 moles of CO, calculate the number of moles of CO2 produced if there is enough oxygen gas to react with all the CO.

Answer 1

4.43 moles CO₂

Step-by-step explanation:

To find the moles of CO₂, you need to multiply the moles CO by the mole-to-mole ratio. This ratio is made up of the coefficients in front of the relevant molecules in the balanced equation. It is important to arrange the ratio in a way that allows for the cancellation of units (moles CO in the denominator).

2 CO(g) + O₂(g) -----> 2 CO₂(g)
^ ^

4.43 moles CO 2 moles CO₂
------------------------ x ----------------------- = 4.43 moles CO₂
2 moles CO
