The osmotic pressure of barium chloride and glucose solution of the...

The osmotic pressure of a solution is given by $\pi = iCRT$.

For the barium chloride solution:
$\pi_{1} = i_{1}CRT = 0.62$ atm

For the glucose solution:
$\pi_{2} = i_{2}CRT = 0.24$ atm

Since glucose is a non-electrolyte, its van't Hoff factor $i_{2} = 1$.

Therefore, $CRT = 0.24$ atm.

Substituting the value of $CRT$ into the equation for barium chloride:
$i_{1} \times 0.24 = 0.62$

$i_{1} = \dfrac{0.62}{0.24} = \dfrac{31}{12} \approx 2.58$

The van't Hoff factor of barium chloride is $2.58$.

Answer: $2.58$
