If the amount of copper that was required to be exported by the employer was 8g calculate the number of amperes that would used for 3 hours?

To calculate the number of amperes used for 3 hours, we need to know the voltage at which the copper is being exported.

Let's assume the voltage is 220V.

First, we need to convert the amount of copper from grams to moles. The molar mass of copper is approximately 63.55 g/mol.

8g of copper is equal to 8/63.55 = 0.126 moles.

Next, we need to calculate the charge transferred in coulombs. Each mole of copper carries 2 moles of electrons, which is equivalent to 2 * 6.022 x 10^23 electrons.

So, the total number of electrons transferred is 0.126 * 2 * 6.022 x 10^23 = 1.51 x 10^23 electrons.

Now, we can calculate the total charge transferred in coulombs using the formula:

Q = n * F

where Q is the charge transferred, n is the number of electrons transferred, and F is the Faraday constant (96,485 C/mol).

Q = 1.51 x 10^23 * 96,485 = 1.46 x 10^28 C

Finally, we can calculate the current in amperes using the formula:

I = Q / t

where I is the current, Q is the charge transferred, and t is the time in seconds.

Since 3 hours is equal to 3 * 3600 = 10,800 seconds, the current is:

I = 1.46 x 10^28 / 10,800 = 1.35 x 10^24 amperes

Therefore, the number of amperes used for 3 hours when exporting 8g of copper at 220V is approximately 1.35 x 10^24 amperes.

There is not enough information to calculate the number of amperes used for 3 hours. I need the electrochemical equivalent of copper and the voltage applied to determine the current (amperes).
