mass NaHCO3 (g)   molar mass NaHCO3 (g/mol)   moles NaHCO3 (mol)   liters solution (L)   Molarity NaHCO3 (M)   . Start Virtual ChemLab, select Reactions and Stoichiometry, and then select Creating a Solution of Known Molarity from the list of assignments. The lab will open in the Titration laboratory.   2. In the laboratory, a bottle of baking soda (sodium bicarbonate, NaHCO3) will be next to the balance, and an empty beaker will be on the stir plate.  Drag the empty beaker to the spotlight next to the balance, click in the Balance area to zoom in, place a weigh paper on the balance, and tare the balance.  3. Open the bottle by clicking on the lid (Remove Lid). Pick up the Scoop and scoop out some sample by first dragging the scoop to the mouth of the bottle and then pulling the scoop down the face of the bottle. As the scoop is dragged down the face of the bottle it will pickup different quantities of solid. Select the largest sample possible and drag the…

9. How many moles of 2 Na(s) * 24- 2. Provide an example calculation for row 8. This requires you to go from g CO2 to g NaHCO3 using stoichiometry. Use equation 2, a net ionic equation for the reaction of acid, H3O* (from acetic acid, CH3COOOH in vinegar) with the bicarbonate (from NaHCO3 in pill) to determine the molar ratio for your calculation. Note that Na+ (aq) doesn't show up in this equation because it is a spectator ion. Hag) H

MTY1103 ANALYTICAL CHEMISTRY - LABORATORY PROBLEM SET 1 I. SOLUTIONS 1. Typical seawater contains 2.7g of salt (sodium chloride, NaCl) per 100mL. What is the molarity of Nacl in the ocean? 2. Copper (II) sulfate pentahydrate, CuSO, 5 H20, has 5 moles of H20 for each mole of CuSO, in the solid crystal. The formula mass of CuSO4 • 5 H20 is 249.68 g/mol. How many grams of CuSO4 • 5 H20 should be dissolved in a volume of 500.0 mL to make 8.00 mM Cu2*? The dissociation equation for the given salt is CuSO4 • 5 H2O -> Cu2* + S0, + 5 H20 3. How many ml of 15.8 M nitric acid should be diluted to 0.250 L to make 3.00M HNO3? 4. Vinegar contains 5 wt% acetic acid. How many grams of vinegar are required to react with 5g of NaHCO3? The density of vinegar is close to 1.0 g/mL. How many mL of vinegar are required to react with 5g of NaHCO3? The reaction of vinegar and sodium bicarbonate is given by the reaction NaHCO3 + CH3COOH → Na* + CO2 + H2O + CH3CO 5. In a gravimetric analysis, we need enough…
