19. 150 mCi of D2O is injected in your patient. 10% of D2O is excreted. The concentration of D2O in a plasma sample is found to be 0.4 mCi/100 ml.

19. 150 mCi of D2O is injected in your patient. 10% of D2O is excreted. The concentration of D2O in a plasma sample is found to be 0.4 mCi/100 ml. is your patient’ s Total Body Water in L? 20. the diffusion coefficient states that: A. the larger the molecular radius of the solute, the slower the rate of diffusion B. the more viscous the solution, the slower the rate of diffusion C. the smaller the molecular radius of the solute, the faster the rate of diffusion D. the more viscous the solution, the faster the rate of diffusion E. the larger the molecular radius of the solute, the faster the rate of diffusion 21 You are experimenting on diffusion rates in lab. Down the center of Beaker A is a semipermeable membrane. On one side of the membrane in Beaker A is a 100mM solution of CaCl2; on the other side is pure water. Down the center of Beaker B is a semipermeable membrane. On one side of the membrane in Beaker B is a 10mM solution of CaCl2; on the other side of Beaker B is pure water. Given these conditions, predict your findings: a) Beaker A would exhibit a faster rate of diffusion than Beaker B b) Beaker B would exhibit a faster rate of diffusion than Beaker A c) Beaker A and Beaker B would have equal rates of diffusion
