An aqueous solution of urea had a freezing point of `-0.52^(@)C`. Predict the osmotic pressure of the same solution at `37^(@)C`. Assume that the molar concentration and the molality are numerically equal. `(K_(f)=1.86)`

Explanation

To solve the problem, we need to determine the osmotic pressure of an aqueous solution of urea given its freezing point depression and the temperature at which we want to find the osmotic pressure. Here are the steps to find the solution:

### Step 1: Calculate the depression in freezing point (ΔTf)
The freezing point of pure water is 0°C. The freezing point of the solution is given as -0.52°C. Therefore, the depression in freezing point is:
\[ \Delta T_f = 0 - (-0.52) = 0.52°C \]
