Base your answers to questions 55 and 56 on the information below and on
your knowledge of chemistry.
A 2.50-liter aqueous solution contains 1.25 moles of dissolved sodium
chloride. The dissolving of NaCl(s) in water is represented by the
equation below.
55 Determine the molarity of this solution. [I]
56
Compare the freezing point of this solution to the freezing point of a
solution containing 0.75 mole NaCl per 2.50 liters of solution. [I]
Answer--> the first solution has a lower freezing point
or
1.25 moles is lower than 0.75 moles |
