Two 1-L beakers, A and B, each containing a different aqueous solution of fructose (a nonvolatile sugar with MW = 180.16 g/mol) are placed together in a box, which is then sealed. The temperature remains constant at 20 °C. Initially, there is 220 mL of solution in A and 650 mL of solution in B. As the solutions stand in the sealed box, their volumes change slowly for a while. When they stop changing, beaker A contains 430 mL and beaker B contains 440 mL. It is then determined that the solution in A is 1.74 M in fructose and has a density of 1.12 g mL-¹. (a) What is the molar concentration of fructose in the solution in beaker B at the end? M (b) Calculate the concentration of fructose in the solution in A at the start. M (c) Calculate the concentration of the fructose in the solution in B at the start. M (d) The vapor pressure of pure water at 20 °C is 17.5 torr. What is the pressure of water vapor in the box at the end, after the volumes have stopped changing? torr
