Measurements show that during the inflow part of a neuron cycle, about 5.6x10^11 Na+ (sodium ions) per meter, each with a charge of +e, enter the axon. How many coulombs of charge enter a 1.5cm length of axon during this process?
The first step is to convert 1.5 centimeters into meters. Then multiply the number of sodium ions per meter with 0.15 meters. Next step is to multiply it with the fundamental quantum of charge which is 1.602*10^(-19). The final answer is 1.3nC.
