Question

How many electrons is 2415 Coulombs?

Answer 1

oh...First you should understand that coulombs is related to Current*time: q=I*t
So you ought to consider the time(s)^-^

Answer 2

No, that's wrong.

Coulomb is a measure of charge and there is no need to relate it to current. (Instead, we define current in terms of charge.)

The charge on an electron is
\[ e = 1.602 \times 10^{-19} \]

Hence the number of electrons required for a charge of 2415 C is
\[ \frac{2415}{e} = \frac{2415}{1.602 \times 10^{-19} = ... \]

Answer 3

No, that's wrong.

Coulomb is a measure of charge and there is no need to relate it to current. (Instead, we define current in terms of charge.)

The charge on an electron is
\[ e=1.602 \times 10^{−19} \]

Hence the number of electrons required for a charge of 2415 C is

\[ \frac{2415}{e} = \frac{2415}{1.602 \times 10^{-19}} = ... \]

Answer 4

...that's right. sorry i mixed up
