Maintaining certain electrolyte concentrations in blood plasma (the liquid part of blood; blood without cells) is extremely important.

Maintaining certain electrolyte concentrations in blood plasma (the liquid part of blood; blood without cells) is extremely important. Abnormal electrolyte concentrations can lead to severe health conditions. One of the dangers from hemolytic anemia is hyperkalemia, a condition where the release of intracellular potassium from lysed erythrocytes leads to increased blood potassium levels. Regular potassium concentration in blood plasma is 4 mM, while the intracellular potassium concentration of erythrocytes is 100 mM. How many erythrocytes have to lyse in order to increase the potassium concentration in blood plasma to potentially lethal concentrations of 7 mM? What percentage of blood cells does this represent? Note: Since erythrocytes don't have any organelles or a nucleus, you can assume that the cytosol has a volume of 85 fL.
