1. Stoich Lab How to answer some of the post lab questions.

2. 2) Using the exact weight of sodium bicarbonate that you measured from the data table, determine the theoretical yield of sodium acetate? (Use stoichiometry) 3) We are not at STP, therefore to convert milliliters to grams; the density of acetic acid needs to be used. The density of acetic acid is, 1.05 g/mL. Using this information and the exact amount of acetic acid that you measured from the data table, determine the theoretical yield of sodium acetate? (Use stoichiometry)

3. 4) In this reaction, which reactant was the limiting and which was the excess? 5) Theoretically, the max amount of sodium acetate that could be produced is? Cant make more than the smallest amount…compare # 2 vs #3 answers Limiting 6) Calculate the actual yield of sodium acetate that you recovered in this lab, using the weight of the empty flask and the weight of the flask after the reaction. Last row-first row Excess Smallest number, #2 vs #3 answers Bigger number, #2 vs #3 answers 7) Using the actual yield of sodium acetate that you calculated in post-lab question 6 and the theoretical yield of sodium acetate that you determined in calculated in post- lab question 5, calculate the percent yield of sodium acetate recovered in this lab: ( #6/#5 ) x 100 9) Using the theoretical yield as the accepted value, determine the percent error. |#5-#6| x 100 #5
