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...

The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration. (a) To relieve dehydration, a patient is given 190. mL/h of IV glucose (C6H12O6) for 2.0 h. What mass (g) of glucose did she receive? (b) If isotonic saline (NaCl) is used, what is the molarity of the solution? (c) If the patient is given 160. mL/h of IV saline for 3.0...

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...
