Question
SM urea solution is to o a aon manioaolido-400 moab) mM solution of NaCI. (200mM NaCI 400 mOsM) n of NaC b. hyperosmotic to a 200 mM c. isosmotic to a 200 mM solution of NaCI. d. isosmotic to a 600 mM solution of NaCl. e, isosmotic to a 0.18 % solution of NaCl. 4. What are the two extracellular fluid compartments in the body? 6. In the diagram below are ECF and ICF compartments separated by a membrane permeable to water and to K Use this as the starting condition for the questions below. CF ICF added solution: 10% KCl 3900 mosmoles 7800 mosmoles 15 liters 30 liters a. What is the osmolarity in the ICF before any KCI solution,is added? One liter of a 10% potassium chloride solution will be added to the ECF. What is the osmolarity of the KCI solution? (molecular weight of K-39.1. C|s 35.5) (KCl has a disassociation constant of 2 meaning each mole becomes 2 osmoles) b.Explanation / Answer
3. option a: hyposmotic to a 200mM solution of NaCl. (200mM NaCl = 400 mOsM)
4. Plasma and Interstitial Fluid
5. a. 260 mOsM
b. 2.68 mOsM
