Calculate the mass of 1 mol of electrons...

Calculate the mass of 1 mol of electrons if the mass of one electron be `9.11xx10^(-31)kg`.

Text Solution

Verified by Experts

1 mol of electrons=`6.022xx10^(23)` number of electrons.
Mass of one electron`=9.11xx10^(-31)kg`
`therefore` The mass of 1 mol of electron
`=6.022xx10^(23)xx9.11xx10^(-31)kg=5.486xx10^(-7)kg`.
