JEE Main 6 April 2026, Shift 2, Chemistry Q55

Question 55 of 75 in this shift, Chemistry question 5 of 25, Section A.

Given below are two statements : Statement I : H2O\mathrm{H_2O} molecules move from the chamber 1 to chamber 2. Statement II : The osmotic pressure of a solution prepared by dissolving 50 mg of potassium sulphate (molar mass = 174 g/mol) in 2 L of water (at 27 °C) is 0.0107 bar. (Given: R = 0.083 dm3^3 bar K−1^{-1} mol−1^{-1} and assume complete dissociation of electrolyte) In the light of the above statements, choose the correct answer from the options given below :
