If the tape pulled from the dispenser has 0.12 μC of charge per centimeter, what length of tape must be pulled to transfer 1.6×1013 electrons to the remaining tape?

Thank you for the opportunity to help you with your question!

1e = 1.6 x10^-19C = 1.6 x10^-13μC

has 0.12 μC of charge per centimeter

pull out 1 cm tape transfer 0.12/(1.6 x10^-13) = 7.5 x10^11 electron to the remain tape. 

so the length is 

1.6 x10^13/(7.5x10^11) cm = 21.3 cm


Please let me know if you need any clarification. I'm always happy to answer your questions.
