Assuming 100% dissociation, 1.0 mol of NaBr dissolved in 250 g of water [ Select ] have the same colligative properties as 1.0 mol of KCI dissolved in 250 g of water, because ( Select]

Two beakers are placed in a sealed box at 25 °C. One beakercontains 30.0 mL of a 0.050 M aqueous solution of a nonvolatilenonelectrolyte. The other beaker contains 30.0 mLof a 0.035 M aqueous solution of NaCl. The water vaporfrom the two solutions reaches equilibrium. (a) In whichbeaker does the solution level rise, and in which one doesit fall? (b) What are the volumes in the two beakers whenequilibrium is attained, assuming ideal behavior?

An experiment was conducted to determine the effect of glucose on the freezing point of water. Experimental data showed thatthe freezing point depression of water in solution was –2.6°C when 1.0 g of glucose was dissolved in 10g of solvent. Calculatethe expected freezing point for such solution and compare the expected freezing point to the value found experimentally. Give aplausible explanation for any discrepancies. (M.W. of glucose= 180.16g/mol; i=1). Show all your work.
