Pick up tо twо (2) оf the following questions to аnswer for а mаximum of 10 points extra credit. Only two choices will be graded. Be sure to indicate which two you are answering or I will grade your responses to the first two answered. 1. A patient's blood test shows that he has a bilirubin level of 0.012 mol/L. How many grams of bilirubin are in 5.0 mL of his blood. The molar mass of bilirubin is 584.66 g/mol. You must show your work to receive credit for this answer. 2. A nitrogen bubble forms in the left knee joint of a deep-sea diver as she comes to the surface. Below sea level, the pressure is 3.15 atm and the bubble has a volume of 0.015 mL. Assuming constant temperature, calculate the volume of this bubble at the surface where the pressure is 1.00 atm. You must show your work to receive credit. 3. The "normal" range for blood pH is 7.35 - 7.45. A patients blood is analyzed for the concentration of H3O+ which was found to be 6.78 x 10-2. Based upon this test, the patient's blood pH would indicate which one of the following: acidosis, alkalosis, or within normal range? Justify your answer.
