Pure water has very few ions (about 1.20 X 1014 ions per cubic centimeter), giving it a high resistivity, about 1.0 X 105 Q-m at 370C. Blood plasma has a much lower resistivity of roughly 0.600 Q-m at 37.0C due to the ions dissolved in the plasma. Assuming the resistivity depends only on the concentration of ions, how many ions per cubic centimeter are in blood plasma? X 1019 ions/cm3
