Stoichiometry Instructions: Complete the following questions and hand in at the start of your lab period or when instructed by your instructor. Show your work with units and correct significant figures for all questions that involve a calculation. 1. Calculate the molecular weights of all the compounds in the reaction we are doing in this lab (and copy them onto your procedure... they will be helpful!): a. NaHCO3 b. HCI c. NaCl d. H₂O e. CO2 2. The following is some example data for the lab. Use the data to answer the following questions. Mass of test tube and boiling chip Mass of test tube, boiling chip and NaHCO3 Mass of test tube, boiling chip and NaCl a. How much NaHCO3 was added to the test tube? 14.123 g 14.724 g 14.496 g b. How many grams NaCl was produced from the experiment? c. Using the balanced chemical equation, the amount of limiting reactant calculated above, and molar masses from question 1, how many moles of NaCl should the experiment have produced? d. Calculate the percent yield for this experiment.
