Answer:
The number of moles of carbon dioxide that would be produced is 2 moles
Step-by-step explanation:
The given reaction is presented as follows;
O₂ (g) + 2CO (g) → 2CO₂ (g)
The parameters given are;
The mass of the carbon monoxide, m₁ = 70.0 g
The mass of the oxygen, m₂ = 32.0 g
The molar mass of carbon monoxide = 28.01 g/mol
The molar mass of oxygen gas O₂ = 32.0 g/mol
The number of moles, n = (The mass)/(The Molar Mass)
The number of moles of carbon monoxide in the reaction = 70.0 g/(28.01 g/mol) = 2.49910746 moles ≈ 2.5 moles
The number of moles of oxygen in the reaction = 32.0 g/(32.0 g/mol) = 1 moles
Therefore, from the chemical reaction, we have;
One mole of O₂ reacts with two moles of CO to produce two moles of CO₂ (g)
1 mole of oxygen produces 2 moles of carbon dioxide
Therefore, given that the number of moles of oxygen in the reaction is 1 mole, we have that the number of moles of carbon dioxide that would be produced = 2 moles.
