Final answer:
A charge of -50.0 μC is made up of approximately 3.119 x 10^13 electrons.
Step-by-step explanation:
The charge of -50.0 μC can be written as -50.0 x 10^-6 C.
The charge per electron, e, is equal to -1.602 x 10^-19 C.
The number of electrons, ne, can be calculated using the formula:
ne = total charge / charge per electron
Substituting the values:
ne = (-50.0 x 10^-6 C) / (-1.602 x 10^-19 C)
ne = 3.119 x 10^13 electrons
Therefore, a charge of -50.0 μC is made up of approximately 3.119 x 10^13 electrons.
