Alamp has a current of 2.17 a. in hours, how long does it take for 1 mole of electrons to pass through the lamp?

The amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.

Explanation:

We are given:

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains number of particles.

We know that:

Charge on 1 electron =

Charge on 1 mole of electrons =

To calculate the time required, we use the equation:

where,

I = current passed = 2.17 A

q = total charge =

t = time required = ?

Putting values in above equation, we get:

Converting this into hours, we use the conversion factor:

1 hr = 3600 seconds

So,

Hence, the amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.
