Question

how many electrons are there in -16 x 10 raise to -19 C

Answer 1

charge on one electron is ⬇

$e = - 1.6 \times {10}^{ - 19}$

and given charge is ⬇

$q = - 1.6 \times 10 \times {10}^{ - 19}$

electron present is ⬇

$n = \frac{q}{e}$

so your answer is ⬇

$n = \frac{ - 16 \times 10 \times {10}^{ - 19} }{ - 1.6 \times {10}^{ - 19} }$

so we get $n_{number of electron}$=10
