A certain single ion channel is selectively permeable to K* and has a resistance of 1.15 GQ, therefore a current of potassium ions through the channel is possible. During an experiment, the channel is open for approximately 1.50 ms while the voltage across the channel is maintained at 81.5 mV. How many K+ ions, N, travel through the channel during this time? N=
