The monovalent salt concentration (the predominant solute in the blood cell) for a sample of red blood cells is 0.19 moles/liter. If one of these red blood cells were placed in pure water (at around room temperature, 300 K), and the cell comes to hydrostatic equilibrium with the water, what is the osmotic pressure of the cell (assuming it doesn't burst)? Provide your answer in kilopascals (1 kPa = 1x103 Pa). Again, be careful, salts dissociate when dissolved, and take care with the concentration (moles/liter vs moles/m3).

blood cell is related to the osmotic pressure in the red blood
cell, then decreasing salt concentrations of the solution will
cause the cell to swell and burst.

Osmotic Pressure: You are trying to make artificial blood cells. You have managed to get pure lipids to form spherical bags (cells) of radius 10 μm, filled with hemoglobin. The first time you did this, you transferred the cells into pure water and they promptly burst, spilling the contents. Eventually you found that transferring them into a 1 mM salt solution prevents bursting, leaving the cell spherical and full of hemoglobin and water. Explain the reason why the cells burst...

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...

1) What is the approx saline concentration of an animal red blood cell? 2) By what process does water move across a cell membrane & does this process require cellular energy? 3) Would you predict a red blood cell placed in a 5.00% saline solution to crenate, lyse, or stay normal? Explain why. What about a red blood cell placed in a 0.10% solution? 4) Why would 2 test tubes with 0.50% saline and 0.05% saline each, become clear after...

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...
