A solution is made by dissolving 0 point 6 1 1 mol of NaCl in 250 g of water. If the molar mass of NaCl is 58 point 4 4 g over mol , what is the molality of the solution? Use molality is equal to moles of solute over kilograms of solvent

Convert the water’s mass to kilograms: 250 g = 0.250 kg. Molality is moles of solute divided by kilograms of solvent, so 0.611 mol ÷ 0.250 kg = 2.444 mol/kg, or about 2.4 m. The correct choice is 2.4 m.
