Best answer: How many moles of electrons weighs 1 kg?

So 1Kg of electrons contain 1.825 x10^6 moles of electrons. 1.8×10^6 moles of electrons weigh 1 kg.

How many moles of electrons weigh 1kg?

Mass of electron = 9.1 x 10-31Kg One mole of electrons = 6.023×1023 Mass of 1 mole of electrons = 6.023×1023 x 9.1 x 10-31Kg We need to find out moles of electrons in 1 Kg Hence out moles of electrons in 1 Kg = 1kg x 1mole/ 6.023×1023 x 9.1 x 10-31Kg =1.825 x 106 moles of electrons.

What is the number of electrons that would weigh 1 kg?

How many electrons are there in 1 kg? Answer: 1.8×10^6 moles of electrons weigh 1 kg.

How many moles are in an electron?

1 mole of electrons contains the Avogadro constant, L, electrons – that is 6.02 x 1023 electrons. You would also be given that in an exam if you needed to use it. This value is known as the Faraday constant.

How is Faraday calculated?

The faraday

  1. Sodium and chlorine are produced during the electrolysis of molten sodium chloride:
  2. 9,650 coulombs of charge pass. Calculate the amount of sodium and chlorine produced. Remember that 1 F (faraday) = 96,500 C.
  3. Number of moles of electrons = 9,650 ÷ 96,500 = 0.1 mol.
