How much negative charge has been removed
from a positively charged electroscope if it has a charge of
7.5x10 -11 C?

jfraser · Answer

faraday's constant links the amount of charge to a $mole$ of electrons:

$$1F = \frac{96,500 C}{1mol e^{-1}}$$since you know what $fraction$ of charge moved, you can use the constant to convert to $moles$ of electrons, and then to a $number $ of electrons

it's 7.5x10^-11 ..bcz if you want to make a positive ion with charge 1 then you have remove one electron means negative charge .and same for the given situation .As given that it has a positive charge 7.5x10^-11 which means we have removed 7.5x10-11 negative charge from electroscope to make that positive charg
