Question

You measured a charge of -25 nc. how many electrons approximately would that correspond to?

Answer 1

A charge of -25 nanocoulombs corresponds to approximately 1.56 x 10^10 electrons, calculated by dividing the total charge by the charge per electron.

Step-by-step explanation:

When a charge of -25 nanocoulombs (nC) is measured, it can be translated into the number of electrons that charge represents. Since the charge of one electron is approximately -1.60 x 10-19 coulombs (C), you can determine the number of electrons by dividing the total charge by the charge per electron. Calculating this gives :

Number of electrons, ne = Total charge / Charge per electron
= (-25 x 10-9 C) / (-1.60 x 10-19 C/e-)
= 1.56 x 1010 electrons.

Therefore, a charge of -25 nC corresponds to approximately 1.56 x 1010 electrons.
