Question

Quizplus · Accepted Answer

To find molality, use the formula: molality = moles of solute / kg of solvent. First, calculate the mass of the solution using its density (1.202 g/mL) and volume (1 L = 1000 mL). Then, find the mass of the solute (Pb(NO3)2) using its molarity (0.726 M) and molar mass. Subtract the mass of the solute from the total mass to get the mass of the solvent in kg. Finally, divide the moles of solute by the mass of the solvent in kg to find the molality.
