Question

The diffusion constant for a particular ion crossing an artificial membrane is 3.40 x10^-16 m^2/s. the membrane has an area of 8.80 x10^-15 m^2 and a thickness of 8.20 nm. on one side of the membrane there is pure water, on the other side there are ions. if 3.50 x 10^4 ions cross the membrane each second, what is the molarity of the ion solution?

Answer 1

The question requires calculating the molarity of ions in a solution, informing on the diffusion of ions through a membrane and relating to principles of cellular biology and electronics.

Step-by-step explanation:

The student's question involves calculating the molarity of an ion solution based on the number of ions crossing a membrane per second and other given physical parameters of the system. The concept of diffusion through a membrane is crucial in this context, as it relates to how ion concentrations establish an equilibrium across the membrane, a principle common to cellular biology and electronics in the context of nerve conduction and the behavior of capacitors.
