Problem set:-

a.John has a fasting blood glucose level of 184 mg/dL. What is the concentration of glucose in his blood. (glucose MW = 180g/mol, mg/dL = mg/100 mL)?

b. John takes part in a water drinking contest and drinks 2 liter of water extremely fast. What is the concentration of glucose in his blood now. Assume he started with 5 liters of blood before the drinking contest.

c. In terms of osmolarity, what is the danger of drinking that much water so fast. What is will happen to the cells in his body?

d. John gets sick from drinking all that water fast, but recovers. He goes to lab the next day and makes a 50 mM solution of NaCl. He believes this NaCl solution has the same osmotic strength as 50mM urea. Is his assumption correct? Please explain (no calculations are necessary but please explain).
