How do i use freezing point and volume markers?
Problem:
A patient has the following volumes of distribution:
deuterium oxide: 40 liters
inulin: 13 liters
Evans blue: 2.8 liters
Her plasma shows a freezing point depression of 0.53 degrees C. For an ideal solution, a 1 OsM solution depresses the freezing point 1.86 degrees C.
1. What is the osmolarity of her body fluids?
2. How much solute (osmoles) exists in each of the above compartments?
