See explanation.
Explanation:
Hello there!
In this case, according to the given information, it turns out firstly necessary for us to set up the equilibrium reaction by which chromium (II) iodide is ionized as follows:
Thus, it is possible to notice that the the moles, and therefore concentrations, of chromium(II) and iodide ions are going to be different, by a factor of 2 due to the mole ratio in the aforementioned chemical equation.

Answer:
The molality of the solution is 3.45 mol/kg
Explanation:
Molality is a type of concentration which shows the moles of solute contained in 1 kg of solvent.
Moles of salt (KCl) = 1.12 moles
Moles of solvent (H₂O) = 18 moles
Let's convert the moles of solvent to mass (mol . molar mass)
18 m . 18g/m = 324 grams
We convert grams to kg → 324 g / 1000 = 0.324 kg
Now we can reach molality
1.12mol / 0.324 kg = 3.45 m
