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

Question

Quizplus · Accepted Answer

To find the limiting reagent, calculate the moles of each reactant. Molar mass of CO is 28 g/mol, so 5 g CO is 0.179 moles. Molar mass of O2 is 32 g/mol, so 5 g O2 is 0.156 moles. The reaction requires 2 moles of CO for every 1 mole of O2. Therefore, CO is the limiting reagent because it will run out first.
