What is the relationship between the molality of a solution and its boiling point elevation?
Step 1: Understand what molality is. Molality is a measure of the concentration of a solution, defined as the number of moles of solute per kilogram of solvent.
Step 2: Learn about boiling point elevation. Boiling point elevation is the increase in the boiling point of a solvent when a solute is added.
Step 3: Know the relationship. The boiling point elevation increases as the molality of the solution increases.
Step 4: Remember the formula. The formula for boiling point elevation is ΔT_b = i * K_b * m, where ΔT_b is the boiling point elevation, i is the van 't Hoff factor, K_b is the ebullioscopic constant, and m is the molality.
Step 5: Conclude that since molality (m) is part of the formula, a higher molality means a greater boiling point elevation.
