Question

If the charge on an electron be 1.6×10-19 C, find the approximate number of electron in 1C ?

Answer 1

hey friend,
heres your answer,
hope it helps you...!

Answer 2

1 electron = 1.6 × 10^-19 Coulomb

Number of electrons = 1 Coulomb × (1 electron) / (1.6 × 10^-19 Coulomb)
= 6.25 × 10^18

∴ There are 6.25 × 10^18 electrons in 1 Coulomb
