forgive me for I'm sure this is an easy mathematical question but I'm just starting out in a course called ELECTRO-Mechanical Technician. I just did an exam, my first in this course, but a question has been bugging me.
the question was 4.91x10^12 electrons are taken out of the flow and then to transfer this into nano. the answer is 787nC.( if I recall accurately).( it is right by the way,787nC, I have the results, but not the specific question, I'm just going by memory)
this what I thought I should do. since 1 C is 6.24x10^18 electrons. I should subtract 4.91x10^12 from 1C , but in order to do so I have to make the exponents the same> so 4.91x10^12 becomes 4,910,000x10^18 - 6.24x10^18 which does not give the above answer.
WHAT I"M I DOING WRONG!!
