Shown below are 6 compounds.  Compounds A and B are ionic with their formula given, while compounds C-F are molecular and their 3-D shape is shown.  Table for Question 13 Letter Identifier A B C D E F Compound NaF FeCl   Match the compounds with their order from lowest to highest melting point. With (1) being the lowest melting point and (6) being the highest boiling point.  

Instead of water, you try to dissolve the salt in the previous question in 2.0 L of a 0.1 M NaSO4 solution.  Would you expect more, less, or the same amount of your salt to dissolve in this solution compared with what you calculated in water?  

You dissolve 25.0 g of solute in enough water to make a solution that has a total volume of 100.0 mL and a density of 0.953 g/mL. Calculate the mass percent of the solution.  Enter numbers and decimal points ONLY.  Enter three significant digits past the decimal point.  Your answer should be four significant digits total. DO NOT enter M, it is known that your answer is in M.
