calculate the osmolarity of the saturate 0.0067 NaCl solution
What is the osmolarity of a solution containing 0.1 M NaNO3 and 0.2 M NaCl?
1) What is the osmolarity of an IV solution which is .45% NaCl and 5% glucose? a. If a patient is dehydrated, what is the best IV to move water into the cells? b. What is the best IV for a patient with severe blood loss before new blood arrives?
What is the osmolarity of a 0.8% solution of sodium chloride (NaCl)? Atomic weights: (Na - 23, CI - 35.5)
1. A batch of cells are found to contain 300 mM glucose and 150 mM CaCl2 inside the cell. The cell membrane has pores which are permeable to glucose but not to ions. These cells are then placed in a NaCl solution which has an osmolarity of 450 milliosmoles. What happens to the cells after the solution comes to equilibrium? a. The cells remain the same size as they were originally b. The cells swell c. The...
Homework #1: Osmolarity/tonicity Problem: A patient has the following volumes of distribution: deuterium oxide: 42 liters inulin: 13 liters Evans blue: 2.8 liters Her plasma shows a freezing point depression of 0.55 degrees C. For an ideal solution, a 1 OsM solution depresses the freezing point 1.86 degrees C. 6. Patient eliminates 0.8 L of sweat that contains 150 milliosmoles NaCl. Total ECF ICF Vol L Sol osmol mOsM Explanation:
1) Suppose you made an intravenous solution, intended to be isoosmotic to red blood cells (i.e., 300 mOsm). You add 5 grams of NaCl to 800 ml of distilled water. Will this solution be isoosmotic to cells? if not, what will happen to the cells? (Will they take in water or lose water?) How would you make 500ml of a 5% NaCl solution? You dissolve 20 grams of glucose into water to give a solution whose final volume is exactly...
What is the molarity of CL- in each solution? a. .200 M NaCl b .150 M SrCl2 c. .100 M AlCl3 WHat I dont understand is how NaCl equates Cl-? Can you explain please
For the following solutions indicate if they are isosmotic with the intracellular fluid of a red blood cell (assume red blood cell osmolarity is 300 mOsm). Also indicate if red blood cells would swell or shrink if placed in a given solution. Solution Osmolarity (Osm) Osmolarity (hyper, iso,hypo) Tonicity (hyper, iso, or hypo) Hemolysis (Yes or No) 150 mM NaCl ddH2O 100 mM NaCl 50 mM NaCl 300 mM sucrose 150 mM CaCl2 300 mM urea 900 mM urea 900...
