I'm having trouble turning mM to mOsmoles. The equation goes like this: red blood cell are placed into a beaker filled with .5L of a 150mM NACL solution. NACL is non-penetrating solute and will not cross the red blood cell membrane.
I have 150mM/0.5L * 2mOsM/100mM
But something isn't adding up since I have to compare it to a red blood cell equal to 300mOm. I keep getting 6000mOsM
