Multiple Choice

A faraday is defined as charge equal to N_A protons.

(Avogadro's Number N_A = 6.02 x 10²³)

Find the number of coulombs in 1 faraday.

(use q_p = 1.6 x 10^-19 C)

A) 96440

B) 96485

C) Not enough inframation

D) 96320

Answer 1

Hey Gabriel,

Knowing the charge (in C) of one proton. you can just multiply that by Avogadro's number to find the total charge.
