- Homework Statement
- The monovalent salt concentration (the predominant solute in the blood cell) for a sample of red blood cells is 0.21 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)? Again, be careful, salts dissociate when dissolved, and take care with the concentration (moles/liter vs moles/m3).
- Relevant Equations
- π=CRT
where:
π is osmotic pressure
C is concentration
R is the constant 8.314 J/Mol*K
T is the temperature at 300 K
I haven't learned what a monovalent salt is, but through some research, I'm assuming it's when a solute like NaCl dissociates into one of each molecule, so C_solute is equal to C_Na + C_Cl.
With that assumption, how do I find C_Na and C_Cl?
If I read the question correctly, the sample of red blood cells is the same as salt (0.21 moles/liter), but then it says the red blood cells were placed in pure water, which is where I am lost.
Again, I'm just confused on what C is.
