Determine the osmotic pressure of a solution prepared by dissolving 0·025 g of `K_(2)SO_(4)` in 2 litres of water at `25^(@)C`, assuming that `K_(2)SO_(4)` is completely dissociated.
`(R=0.0821 " Lit-atm K"^(-1) "mol"^(-1)," mol. wt. of " K_(2)SO_(4)=174"g mol"^(-1))`

Explanation

To determine the osmotic pressure of a solution prepared by dissolving 0.025 g of \( K_2SO_4 \) in 2 liters of water at \( 25^\circ C \), we will follow these steps:

### Step 1: Calculate the number of moles of \( K_2SO_4 \)

The formula to calculate the number of moles (\( n \)) is given by:

\[
n = \frac{m}{M}
