All multiple parts to the same problem, thank you! :)
Solution Stoichiometry: We need to make a 0.250 M sodium carbonate solution. We will use a 100.00 mL volumetric flask. How many grams of solid sodium carbonate should we add to the flask to make the solution? Use 105.99 as the molar mass, report correct sig figs, and use g as the unit. Solution Stoichiometry: We need to make a 0.200 M calcium chloride solution. We will use a 100.00...

Write a balanced chemical equation for the reaction between calcium chloride and potassium carbonate. Using stoichiometry, calculate the limiting reactant and the theoretical yield (the mass of CaCO3 product) for the reaction. What is the actual yield of CaCO3(s) formed from your experiment? Show your work. Determine the percent yield of the reaction.
