2. Using the exact weight of sodium hydgrogen carbonate that you measured in step 1 and the equation that you wrote in the problem above, what is the theoretical yield of this reaction?

3. Calculate the actual yield of sodium acetate that you recovered in this lab, using the mass of the empty flask and the mass of the flask after the reaction.

4. Usin the actual yield of sodium acetate that you measured in step 3 and the theoretical yield of sodium acetate that you calculated in step 2, calculate the percent yield of sodium acetate recovered in this lab.

5. Was your percent yield of sodium acetate 100%? What factors do you think caused any error that you found? Expalin, using specific examples.

6. Do you think it is common for chemists to get 100% yields for chemical reactions? Why or why not?
