What is the molality of a solution containing 3 moles of solute in 1 kg of solvent? (2022)

What is the molality of a solution containing 3 moles of solute in 1 kg of solvent? (2022)

Step 1: Identify the number of moles of solute. In this case, there are 3 moles of solute.
Step 2: Identify the mass of the solvent in kilograms. Here, the mass of the solvent 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.
