Text Solution

AI Generated Solution

To solve the problem step by step, we will use the concepts of vapor pressure and molality. ### Step 1: Understand the given data - The vapor pressure of pure ethyl alcohol (P₀) at 25°C = 59.2 torr - The vapor pressure of the urea solution (Pₛ) = 51.3 torr ### Step 2: Calculate the lowering of vapor pressure The lowering of vapor pressure (ΔP) can be calculated as: ...
