How many moles of electrons are given by (i) 9860 C (ii) a current of 1.5 A for 30 s ? =0.0928 mol electrons .

## How many moles are in Zn fes2?

In the given molecule , 1 mole of Zn , 2 moles of Fe and 4 moles of S are present. Hence, we conclude that the Fe is the limiting reagent. Now we have to calculate the moles of . Therefore, the moles of is, 0.027 moles.

## How many moles of electron is needed for reduction of each mole of Cr in the reaction?

Cr has a oxidation state of +5 and it requires 5 electrons for its reduction. So 5 moles of electron is needed for the reduction of each mole of Cr in the reaction.

## How many moles of electrons are transferred?

Current (A = C/s) x time (s) gives us the amount of charge transferred, in coulombs, during the experiment. Using the faraday constant, we can then change the charge (C) to number of moles of electrons transferred, since 1 mol e= 96,500 C. Now we know the number of moles of electrons transferred.

## How many electrons are in a mole?

One mole of anything is 6.022 x 10^23 particles. That’s what a mole is and 6.022 x 10^23 is the Avogadro number. So, 1 mole of electrons is 6.022 x 10^23 electrons.
