SUMMARY
The discussion focuses on calculating the number of moles of electrons that weigh 1 kg. The mass of an electron is established as 9.1 x 10-31 kg. To find the number of electrons in 1 kg, the calculation involves dividing 1 kg by the mass of an electron, resulting in approximately 1.1 x 1030 electrons. Subsequently, this number is divided by Avogadro's number (6 x 1023) to determine the number of moles of electrons, confirming that the initial approach was correct without needing to convert units.
