The osmotic pressure of a solution containing `5 g` of substance (molar mass =100) in 308 m L of solution was found to be 4.0 atm at `300 K`. Calculate the value of solution constant (R)

Explanation

To calculate the value of the solution constant \( R \) using the given data, we can follow these steps:

### Step 1: Write down the formula for osmotic pressure
The formula for osmotic pressure (\( \pi \)) is given by:
\[ \pi = CRT \]
where:
