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
