AI Generated Solution

To calculate the molality of an aqueous urea solution with a mole fraction of urea (X_urea) equal to 0.2, we can follow these steps: ### Step 1: Understand the Definition of Molality Molality (m) is defined as the number of moles of solute (urea) per kilogram of solvent (water). The formula for molality is: \[ m = \frac{\text{moles of solute}}{\text{mass of solvent in kg}} \] ...
