Question

How many electrons make up 1.50 coulomb of charge? (Hint: q = ne.) answer in:_____electrons

Answer 1

We are asked to determine the number of electrons in 1.5 Coulomb of charge. To do that we will use the following formula:

$q=ne$

Where:

$\begin{gathered} q=\text{ charge} \\ n=\text{ number of electrons} \\ e=\text{ fundamental charge of electrons} \end{gathered}$

The fundamental charge is the charge of 1 electron and is given by:

$e=1.6\times10^{-19}C$

Now, we substitute the values:

$1.5C=n(1.6\times10^{-19}C)$

Now, we solve for "n":

$\frac{1.5C}{1.6\times10^{-19}C}=n$

Solving the operations we get:

$9375000000000000000=n$

Therefore, there are 9375000000000000000 electrons.
