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.

Multiply by Avogadro's Number Therefore, the value calculated in the previous step is the energy of one particle; multiply it by Avogadro's number to determine the energy of one mole. (3.9 x 10^-19)*( 6.02 x 10^23)= 2.3 x 10^5 joules.

To find the mole count, divide the mass in grams by 2.016. For example, if the mass of the hydrogen gas is 0.5 grams, then n equals 0.2480 moles. Convert the temperature T into Kelvin units by adding 273.15 to the temperature in Celsius. Use the ideal gas equation (PV=nRT) to solve for pressure.

To calculate the moles of solute you will need to divide the weight in grams you have added to the solution by the weight in grams of one mole. For this example, use sodium chloride: NaCl. The weight of one mole, rounded to the nearest tenth, is the atomic weight of sodium, 23g, plus the atomic weight of chorine, 35.5.

Re: Determining n in G=-nFE To find this, you need to balance the half reactions and then balance the half reactions against one another in order to determine the number of moving electrons. When we balance the half reactions we set the number of electrons equal to one another.

Depending on the atomic mass, you can calculate the number of atoms, and by knowing the number of electrons in the various orbits of each atom, you can find out the total number of electrons. If you were asking for 1 kg of electrons and it's count, then 'n'= 10/(9.11*10^-31)= approximately 10^31 electrons.

This is defined as one Faraday. You mean: How I calculate the charge on one mole of electrons. Well, the charge on a single electron is 1.6 x 10^-16 Coulomb, and there are 6.02 x 10^23 electrons per mole, so the charge will be (1.6 x 10^-16) x (6.02 x 10^23) = 96500 C which is called 1 Faraday.

Mass of an electron= 9.1 x 10^-31 Kg. Avagadro Number=6.022 x^10^23. =1.825 x 10^6 moles of electrons. So 1Kg of electrons contain 1.825 x10^6 moles of electrons.
