Final answer:

By using stoichiometry and the molar masses of the reactants, we can calculate the grams of potassium carbonate produced from 224.4 g of KOH and 88.0 g of CO₂.

Step-by-step explanation:

To determine the amount of potassium carbonate formed, we need to consider the mole-to-mole ratio between the reactants and the product in the balanced chemical equation. Potassium hydroxide (KOH) reacts with carbon dioxide (CO₂) to form potassium carbonate (K₂CO₃) and water (H₂O). The given masses are 224.4 g of KOH and 88.0 g of CO₂, also noting that the reaction produces 36.0 g of water. To find the grams of potassium carbonate produced, we would use the molar masses of KOH and CO₂ to convert the given masses to moles, and then use the stoichiometry of the balanced equation to determine the moles of K₂CO₃ formed. Finally, we would convert the moles of K₂CO₃ back to grams using its molar mass.
