We already calculated the molality using the formula:

$m = \frac{\Delta T_f}{K_f} = \frac{0.32 \, \text{K}}{1.86 \, \text{K/m}} \approx 0.172 \, \text{mol/kg}$

Thus, the molality of the solutes in the solution is approximately $0.172 \, \text{mol/kg}$. If you need a more detailed explanation or have additional questions, please let me know!

Here are some related questions you might find useful:

1. What is the difference between molality and molarity, and when is each used?
2. How does freezing-point depression relate to colligative properties?
3. How would the calculation change if the solute were an electrolyte that dissociates in solution?
4. What is the significance of the freezing-point depression constant ($K_f$)?
5. How can you determine the molar mass of a solute using freezing-point depression?

Tip: Always double-check units when performing calculations involving colligative properties to ensure consistency and accuracy.
