Question: If 5 moles of KCl are dissolved in 1 kg of water, what is the molality of the solution?

Options:

  1. 5 m
  2. 2.5 m
  3. 10 m
  4. 1 m

Correct Answer: 5 m

Solution: 

Molality (m) = moles of solute / kg of solvent = 5 moles / 1 kg = 5 m.

Questions & Step-by-Step Solutions

If 5 moles of KCl are dissolved in 1 kg of water, what is the molality of the solution?
  • Step 1: Identify the number of moles of the solute (KCl). In this case, it is 5 moles.
  • Step 2: Identify the mass of the solvent (water) in kilograms. Here, it is 1 kg.
  • Step 3: Use the formula for molality, which is molality (m) = moles of solute / kg of solvent.
  • Step 4: Plug in the values into the formula: m = 5 moles / 1 kg.
  • Step 5: Calculate the result: 5 moles / 1 kg = 5 m.
  • Molality – Molality is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per kilogram of solvent.
