An electron has a charge of - 1.6 * 10-19

c. how many electrons would be needed to produce a net charge of - 5.5 * 10-7 c? round the final answer to one decimal place.

-4.8 x 10^-6 / - 1.6 x 10^-19 electrons

turns to

3 x 10^13 electrons

electrons are negatively charged

an electron has a charge of - - 1.6 x 10⁻¹⁹ C

the net charge to be produced is - 5.5 x 10⁻⁷ C

net charge is produced by several number of electrons

to find the number of electrons required - divide the net charge by the charge of 1 electron

number of electrons = - 5.5 x 10⁻⁷ C / - 1.6 x 10⁻¹⁹ C = 3.4 x 10¹² electrons

answer is 3.4 x 10¹² electrons
