Answer

lons to be transported = (10 mM)(100um³) (N) = (0.010 mol)(10-13 L)(6.02×1023 ions mol) =(6.02 x 106 ions) because 100 ionophores are present, every one of them need to transport value of 6.02× 106 ions. Hence the time needed would be (6.02 x 106 ions) (1sec/104 ions) = 602 seconds or 10 minutes.
