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 20C. Initially, there is 160mL of solution in A and 760mL 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 420mL and beaker B contains 500mL. It is then determined that the solution in A is 0.758M in fructose and has a density of 1.05gmL1. (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. (c) Calculate the concentration of the fructose in the solution in B at the start. M (d) The vapor pressure of pure water at 20C is 17.5 torr. What is the pressure of water vapor in the box at the end, after the volumes have stopped changing
