Chem help PLEASE!?!?!?!?!

I have this to write up for my Chem class. My brain is on total overload and I just may be heading to that "burn out" point! Perhaps 16 credits was a bit too much for this semester........If anyone could help me out I would really appreciate it!!

As a nurse, why is it important to understand

solutions and solution concentrations? Why would a medical professional be concerned about osmosis

and how it works?

In my answer I must touch on the following subjects:

equilibrium

solution an electrolyte or non electrolyte

osmotic pressure

direction the solvent will travel using osmosis

how boiling and freezing point will change properties of solutions

define a mole

calculating molar mass and molecular mass

how to calculate the number of moles

given the grams and the number of grams given the moles

how to calculate concentrations including

w/w percentages, molarity, and dilutions

- the processes that affect the movement of water and electrolytes

between the ICF and ECF and the effect on cells by the fluid that surrounds them.

(normally the ICF and ECF are isotonic so there will be no net movement of water; no net gain or loss of water; but if the cell is surrounded by hypotonic fluid then the water moves into the cell and causes it to swell or burst; if the cell is surrounded by hypertonic fluid then the water moves out of the cell and dilutes the ECF so that the cell will shrink)
