A 5% (w/v) solution of cane sugar (Molar mass = 342 g/mol) is isotonic with a 1% (w/v) solution of an unknown non-electrolyte solute. The molar mass of the unknown solute is:
The osmotic pressure of a 0.1 M solution of \(K_4[Fe(CN)_6]\) at 27 \(^\circ\)C is (assuming complete dissociation, R = 0.082 L atm mol\(^{-1}\) K\(^{-1}\)):
Which of the following 0.1 M aqueous solutions will have the highest osmotic pressure?
At 300 K, 36 g of glucose (Molar mass = 180 g/mol) is present in 500 mL of its solution. What is the osmotic pressure of the solution? (R = 0.082 L atm mol\(^{-1}\) K\(^{-1}\))
Which of the following statements about osmotic pressure is INCORRECT?
Two solutions, A and B, have osmotic pressures of 2.5 atm and 4.0 atm, respectively, at the same temperature. If solution A is separated from solution B by a semi-permeable membrane, what will be the net direction of solvent flow?
