What current is flowing in a metal wire if 3.0*10^18 electrons pass a given point in a time of 0,10s?

I know that 1 electron has a charge of 1.60*10^-19

I also know that one coulomb is 6.24*10^18

Lastly I know to find current I need to use the formula Q=I*t, but change it to I=Q/t (I= current in Amps, Q= # of electrons or quantity of charge in coulombs, and t= time.

I attempted the solution and this is what I got:

In order to find the current I first need to figure out the quantity of charge (Q).

Q=the number of electrons.

So I multiplied the charge of one electron by the number of electrons in the circuit.

(1.60*10^-19)*(6.24*10^18)= 0.00048 C

Q= 0.00048 C

Now I used the formula I=Q/t

0.00048/10=0.000048.

I= 0.000048 A

Therefore the current in the circuit is 0.000048 A.

All I wanted to know is if I did it correctly and if I did it incorrectly how I could solve it.

Thank you so much in advance :)
