Question

Number of electrons in one columb of charge

Answer 1

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

$1.6 \times {10}^{ - 19} coulmb = 1e {}^{ - } \\ 1coulomb = 1e {}^{ - } \\ 1.6 \times {10}^{ - 19 } \\ 1coulomb = 0.625 \times {10}^{ - 19}$

so there are 0.625×10^-19 electrons in one negative charge
