Suppose you are running a trial of the reaction in Part A. You use 2.80 g of NaHCOs, and determine that 2.83 g of carbon dioxide are produced. Using these data and a periodic table, show calculations to: a. (1.5 pts) Convert the mass of NaHCO, to moles using the molar mass of NaHCO,. Report your answer to three significant figures b. (1.5 pts) Convert the mass of CO; to moles using the molar mass of CO:. Report your answer to three significant figures c. (1.5 pts) Find the simplest ratio between the number of moles of NaÅHCO, and CO. (Hint: divide both numbers by the smaller of the two to get a ratio.) The mole ratio of NaHCO, to CO; is therefore: to d. (1.5 pts) Compare this ratio to the ratio of the coefficients for NaHCO; and CO; in the three balanced chemical equations that are given on page #1. Which of the three possible reactions discussed is consistent with these results? Write the equation in the space below Note: The result in question #3 part c above is not necessarily the correct answer for the experiment in this lab. It is a hypothctical situation for practicing the calculations required in this lab. Do not use this actual result in the lab. Page 8 of 8
