The osmotic pressure of barium chloride and glucose solution of the same concentration at the same temperature are respectively 0.62 atm and 0.24 atm. Calculate the van't Hoff factor of barium chloride.

Step-by-step solution

The osmotic pressure of a solution is given by = iCRT . For the barium chloride solution: ₁ = i₁CRT = 0.62 atm For the glucose solution: ₂ = i₂CRT = 0.24 atm Since glucose is a non-electrolyte, its van't Hoff factor i₂ = 1 . Therefore, CRT = 0.24 atm. Substituting the value of CRT into the equation for barium chloride: i₁ 0.24 = 0.62 i₁ = 0.62 0.24 = 31 12 2.58 The van't Hoff factor of barium chloride is 2.58 . Answer: 2.58
