A red blood cell has a disk diameter of 0.6 micrometers and anintracellular isotonic osmolarity of 290mOsmol/l at a temperatureof 293 kelvin. The hydraulic permeability of the red blood cell is2.4 micrometer atm^-1min^-1 with a b inactivefraction intercept of 0.2. Calculate the normalized cell volume andplot it against osmolarity variations between 50mOsm to 850mOsm.Plot another graph that represents cell volume variations againsttime when the extracellular isotonic osmolarity varies from290mOsmol/l to 990mOsm/l.

For an ideal solution where interparticle interaction doesntexist the solution can be modeled similar to an ideal gas Hencewe have a vant Hoff equation which stateswhere P is the osmotic pressure V is the volume of the solution nis the moles of solute molecules present R is the gas constant andT is the temperature of the solution in KelvinThe equation can be rearranged to obtainnow where is the osmolarity of the See Answer
