A 70 kg subject has a total body water of 40 liters, with 25 liters in the intracellular compartment (ICF) and 15 liters in the extracellular compartment (ECF). The osmolarity of both the ECF and ICF is 290 mOsm/liter, initially. Subsequently, this person drinks 200 ml of 0.333 M CaCl2 which is completely absorbed from the gastrointestinal tract into ECF. (MW of CaCl2 = 111.7, i=2.1) What will the osmolarity of the ECF compartment be prior to osmosis occurring? Assume that the CaCl2 solution is evenly distributed throughout the ECF compartment and that the cell membranes are completely impermeable to Ca++ and Cl-. What will the ECF and ICF volumes be after equilibrium is established?
