Assume an axon has the same characteristics as the class example except the radius of the axon is 0.005 mm and the membrane thickness is 20.0 nm. The percentage fractional change in the concentration of Na+ ions in the axon during one action potential is %? Record the answer to the nearest one thousandth.
