Calculate,
1. Moles of potassium carbonate used.
2. Moles of potassium chloride and moles carbon dioxide produced.
3. Mass of potassium chloride produced.
4. Compare experimental amount of potassium chloride produced to theoretical amount of potassium chloride produced. Use the % yield formula, % yield = experimental amount / theoretical amount. % yield should always be less than 100, or else something went wrong.
