If 0.2 mol of solute is dissolved in 500 g of solvent, what is the molality?

Answer and explanation

Correct answer: 0.4 mol kg⁻¹

Molality is calculated using the mass of solvent, not the total mass or volume of the solution. First convert 500 g of solvent into kilograms: 500 g = 0.500 kg. Then apply m = moles of solute / kilograms of solvent. Thus m = 0.2/0.5 = 0.4 mol kg⁻¹. Therefore, option C is correct. The solute amount is already given in moles, so no further conversion is required.
