Complete the (aq) dissolution equations for each solute, identify the solution as electrolyte or not (EL: Y ? N), and use the molarity of solute formula given to find the total molarity of all solute c.p’s present in that solution. Follow the example in the first row:  Solute balanced c.p’s in (aq) state EL: Y?N molarity of solute formula total molarity of all solute c.p’s in solution CaCl2(s) Ca2+(aq) + 2Cl–(aq) Y 0.20 M 0.2 + 2 × 0.2 = 0.6 M Li2SO4(s)     0.45 M   Mg(ClO4)2(s)     0.2 M

Suppose you want to measure the amount of glucose in a can of soda. You can use the data generated in this experiment to help you, but what other data would you need to collect in order to measure the concentration of glucose in the soda? In other words, what additional experimental step(s) would you perform? B I U Ꭶ X X, 14▾ A In order to measure the amount of glucose in a can of soda, one would need to prepare a series of standard solutions w/ an unknown concentrations of glucose using the 0.3M of glucose sol'n and DI water. Therefore, the glucose oxidase assay would be performed on each standard sol'n and the result values would also be measured by a spectrophotometer. A standard curve may then be plotted by absorbances and the unknown concentration of glucose. It may also be necessary to adjust the pH of the soda can sample to preform additional steps. Change Submission Submitted. Waiting on graded response. 14) Once you have collected data from the step(s) proposed in the previous…

A solution was prepared by dissolving 0.687 g of sulfur, S, in 100.0 g of acetic acid, HC2H3O2. Calculate the freezing point and boiling point of the solution. (K, = 3.08°C/m and Kf = 3.59°C/m, T, = 118.5°C and T† = 16.60°C) Freezing point: °C Boiling point: °C
