What osmotic pressure would 1.25 molal sucrose solution exhibit at `25^(@)C`? The density of the solution is `1.34 g//ml`

Explanation

To find the osmotic pressure of a 1.25 molal sucrose solution at 25°C, we can follow these steps:

### Step 1: Understand the definition of molality
Molality (m) is defined as the number of moles of solute per kilogram of solvent. In this case, we have a 1.25 molal sucrose solution, which means there are 1.25 moles of sucrose in 1 kg (1000 g) of solvent.

### Step 2: Calculate the mass of sucrose
To find the mass of sucrose, we need to know the molar mass of sucrose (C₁₂H₂₂O₁₁). The molar mass of sucrose is approximately 342.3 g/mol.
