At `25^@C`, the osmotic pressure of human blood due to the pressure of various solutes in the blood is 7.65 atm. Assuming that molarity and molality are almost same, calculate the freezing point of blood. `K_"f"=` 1.86 K kg/mol.

Explanation

To calculate the freezing point of human blood based on the given osmotic pressure, we can follow these steps:

### Step 1: Calculate the molarity (C) of the solution using the osmotic pressure formula.
The formula for osmotic pressure (π) is given by:
\[ \pi = C \cdot R \cdot T \]
Where:
...
