Hello there!
In this case, for these problem about the colligative property of freezing point depression, it is possible set up the following equation:
Whereas the van't Hoff's factor, i, is 2 since KCl is ionized in two ions (K+ and Cl-); and the molality (m) of the solution is computed by:
Thus, since the freezing point of water (ice) is 0°C, we obtain the following freezing point of the solution by plugging in:

See figure 1
Explanation:
For this question, we have to remember that definition of an <u>"isomer"</u> in an isomer we have the<u> same condensed formula</u> (in this case ) and <u>different structures</u>. The first structure is a linear structure of 6 carbons (<u>hexane</u>). Then we can have a 5 carbon linear structure in which we have to add a methyl group. This methyl group can be attached to carbon 2 or carbon 3 (<u>2-methylpentane and 3-methylpentane</u>). Finally, we can have a 4 carbon linear structure in which we have to add 2 methyl groups. We can do this addition in carbon 2 (<u>2,2-dimethylbutane</u>) or we can do this addition in carbon 2 and carbon 3 (<u>2,3-dimethylbutane</u>).
