If 5 grams of CO and 5 grams of O₂ are combined according to the reaction, which is the limiting reagent? 2CO + O₂ → 2CO₂

Question

Quizplus · Accepted Answer

To determine the limiting reagent, we first need to calculate the moles of each reactant. The molar mass of CO (carbon monoxide) is approximately 28.01 g/mol (12.01 for carbon + 16.00 for oxygen), so 5 grams of CO is about 5 / 28.01 ≈ 0.178 moles. Without the exact molar mass of O₂ (which seems to be a typographical error or a placeholder for a chemical compound), we cannot calculate its moles directly. However, the question implies a stoichiometric reaction where 2 moles of CO react with 1 mole of the other compound. Given the equal masses and likely higher molar mass of the second compound, CO will be the limiting reagent because it has fewer moles available for the reaction based on the provided stoichiometry.
