The human red-blood-cell membrane is freely permeable to water but not at all to sucrose. The membrane forms a completely closed bag, and it is found by trial and error that adding the cells to a solution of a particular concentration of sucrose results in neither swelling nor shrinking of the cells. In a separate experiment, the freezing point of that particular sucrose solution is found to be -0.56βC. If the exterior of the cell contains only KCl solution, estimate the KCl concentration. Assume that the membrane is also impermeable to KCl. If these cells are suspended in distilled water at 0βC, what would be the internal hydrostatic pressure at equilibrium, assuming that the cell did not change volume?---This is the all the information I'm given, I'm not even exactly sure where to start here.
