A certain liquid x has a normal freezing point of -8.10 °c and a freezing point depression constant K₁=2.69 °C kg mol. A solution is prepared by dissolving some glycine (C₂H,NO₂) in 600. g of x. This solution freezes at -10.4 °c. Calculate the mass of C₂H₂NO₂ that was dissolved. Round your answer to 2 significant digits. g x10

Beyond the Course: Your beverage company is branching out from added sugar in their beverages to make a drink where the main ingredient is fresh-squeezed orange juice, called Beverage C. Yum! The beverage will still be subjected to the same taxes as Beverages A & B, so determining sugar content is still vital. Suggest a method of reliably examining the sugar concentration in each batch of Beverage C. Some considerations to address: Do you want to measure the same property for Beverage C as you did for Beverages A & B? ● Can you use the same calibration curve as you did for Beverages A & B? Describe the considerations you made when determining your method.

Questions 15-21 concern the reaction 2 SO2(8) + 102(8) 22 SO3(g), the crucial step in the production of sulfuric acid. For this reaction AH° = -198 kJ/mol and AS° = -0.187 kJ/mol·K. SO2 (perhaps from the production of copper metal) is mixed with air and heated, resulting in the formation of SO3. (All concentrations are in Kolks units.)
