Solution Stoichiometry: The next step in the lab is to carefully measure out 25.00 mL of the 0.250 M Na2CO3 solution, and 30.00 mL of the 0.200 M CaCl2 solution, and mix them together. Use Reaction Stoichiometry to predict the limiting reactant in the reaction, and the amount in grams of calcium carbonate that we expect to precipitate (theoretical yield). Remember: M= mols solute / L solution Use the following table to help organize your information. 0.250 M Na2CO3 00.200M...
