What is the molality of a solution formed by dissolving 1.12 mol of kcl in 16.0 mol of water?

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
