Mass of 5.0 x 10¹⁸ is 3.0115×10¹⁰g
Electron is the subatomic particle which is denoted by e⁻
Explanation:
In 1897 J J Thomson discovered the electron on the basis of the experiments done with cathode rays
The mass of an electron is nearly 9.11 × 10 -28 g.
Given in question
mass of 5.0 x 10¹⁸ electrons is
The Weight of one mole of the electron is 5.0 x 10¹⁸×9.1×10⁻³¹×6.023×10²³
on calculating the given values we get mass of electrons as
=3.0115×10¹⁰g
