Question

calculate the number of electrons in 4.2 coulomb
charge​

Answer 1

Explanation:

A single electron has a charge of 1.60217733 × 10-19 Coulombs. A collection of 6.2415 × 1018 electrons has a charge of one Coulomb (1/1.60217733x10-19). 1.6 into 10 raise to power -19 no of electrons are present in one coulomb of charge

Answer 2

Q=ne

where,n=no. of electrons

e=charge of electron

∴ e =1.6 × 10−19 C

4.2C = n
