Two compartments are separated by a semi-permeable membrane. in the left hand compartment is the sodium salt of a protein nap. assume nap dissociates completely to na+ and p-. the initial concentration of sodium ion in the left hand chamber is 0.0100m. in the right hand chamber is a nacl solution in which the initial concentration of sodium is 0.100m. the membrane is impermeable to the protein p- but fully permeable to the na+ and cl-. all concentrations in this problem can be given in molarity (m) units.
a. calculate the equilibrium concentration of chloride ion in the left hand compartment. give answer in units of molarity.
b. calculate the equilibrium concentration of chloride ion in the right hand compartment. give answer in units of molarity.
c. calculate the equilibrium concentration of sodium ion in the right hand compartment. give answer in units of molarity.
d. calculate the equilibrium concentration of sodium ion in the left hand compartment. give answer in units of molarity.
e. calculate the net osmotic pressure across the membrane. give your answer in si units. t=310k.
f. calculate the donnan potential. use si units. again assume t=310k.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5ļ°c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/gādegree c). calculate the calorimeter constant. (smĪ“t)warm water = -[(smĪ“t)cold water + (calorimeterĪ“tcold water)]
