can anyone help me with this chemistry question

Question

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

 

 2CO(g) + O₂(g) → 2CO₂(g)

 

Calculate the number of moles of CO₂ produced if 2.36 moles of CO are reacted with excess oxygen.

 moles CO₂

 

Determine the moles of oxygen required to react with the CO.

 moles O₂

Answer 1

 2CO(g) + O₂(g) → 2CO₂(g) ... balanced equation for combustion of CO(g)

From the balanced equation, you can see that 2 moles of CO react with 1 mole of O₂ to produce 2 mols CO₂.

Using these mole ratios we can calculate the answer to the questions being asked as follows:

Calculate the number of moles of CO₂ produced if 2.36 moles of CO are reacted with excess oxygen.

2.36 mols CO x 2 mols CO₂ / 2 mols CO = 2.36 moles CO₂

Determine the moles of oxygen required to react with the CO.

2.36 mols CO x 1 mol O₂ / 2 mols CO = 1.18 mols of O₂
