1. Calculate the theoretical yield of the solid precipitate if we react 2.50 g of K₂CO₃ and 2.00 g CaCl₂.

The molar masses of K₂CO₃, CaCl₂, and CaCO₃ are 138.21, 110.98, and 100.09 g.

2. Calculate the percent yield of the solid precipitate. The actual yield of the reaction is 1.60 g.

3. Based on the actual yield, calculate the mass of calcium present in the original solution.

4. Determine the experimental concentration, %(w/v), of calcium chloride in the solution using the experimental yield of the reaction. Note that the solution has a volume of 50 mL.

5. Calculate the theoretical concentration of calcium chloride.

6. Calculate the percent error between the theoretical and actual percent concentrations of calcium chloride in the solution.
