For 1 g-ion. 1 g-ion = (weight in grams of sum of atomic weight of atoms making the ion.) Here N^3- has 14 amu so 1g-ion 14 gm. Therefore 6.022 × 10^23 ions has = 6.022 × 10^23 ×1.6 ×10^-19 × 3 C = 2.89 × 10^5 C.

1×96500 C.

## What is the charge of 1 mole of electrons?

Charge on a single electron is 1.6 x 10^-16 Coulomb. There are 6.02 x 10^23 electrons per mole. So we get the charge on one mole of electrons as (1.6 x 10^-16) x (6.02 x 10^23) = 96500 C which is also called 1 Faraday.

## How many coulombs are required to produce 50g of Al from molten al2o3?

Thus, 535575 C of electricity will be needed to deposit 50g of Aluminium.

## How much charge is required for the reduction of 1 mole of CU?

## What is coulomb equal to?

The coulomb, also written as its abbreviation ‘C’, is the SI unit for electric charge. One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge on 6.241 x 1018 protons. The charge on 1 proton is 1.6 x 1019 C.

## How do you calculate coulombs?

Charge in Coulombs = Current in Amperes × Time in Seconds

If a current of 30 A flows for 50 s, then the electrical charge in the circuit is 1500 C.
