How many electrons are necessary to produce 1.0 c of negative charge? (e = 1.60 ã 10-19 c)?

Explanation:

The charge on the electron is given as,

And we know that the formula for charge is,

Here,

Therefore,

Therefore the number of electron which necessary to produce 1 C of negative charge is .

The number of electrons required for charge is electrons.

Further Explanation:

An electron is considered to be the most basic unit of charge. The amount of charge carried by an electron is the minimum quantized charge. The electrons carry the negative charge whereas the protons carry the same amount of the positive charge.

The charge on an electron is .

Write the expression for the amount of charge carried by a number of electrons.

Here, is the amount of charge, is the number of electron and is the amount of charge on an electron.

Substitute the value of the amount of charge and the charge on an electron in above expression.

Thus, the number of electrons required for charge is electrons.
