Question

The number of electrons that have total charge of 965 coulombs is
(a) 6.022 x 10²³
(b) 6.022 x 10²²
(c) 6.022 x 10²¹
(d) 3.011 x 10²³

Answer 1

The quantity of electrons that have add up to charge of 965 coulombs is 6.022 x 10²³.

Add up to electrons in kg of electrons: n e = 1 m e = 1.1 × 10 30 electrons.

The mass of an electron is 9.11×10−31 kg, so you require 1.10*10^30 electrons to get a mass of 1 kg.

Their aggregate charge will be 1.10*10^30 times that of a solitary electron, or, in other words Coulomb.
