What is the molality of a solution containing 3 moles of KCl dissolved in 1 kg of water?

What is the molality of a solution containing 3 moles of KCl dissolved in 1 kg of water?

Step 1: Identify the number of moles of the solute (KCl). In this case, it is 3 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 = 3 moles / 1 kg.
Step 5: Calculate the result: 3 moles divided by 1 kg equals 3.
Step 6: State the final answer: The molality of the solution is 3 m.
