Question

A collection of 0.55g of electron is equal to
​

Answer 1

Answer:

Mass of one electron - 9.1×10^-28 gm.

So. No. of electrons in 0.55 gm electron

= 0.55÷(9.1×10^-28)

= 6.04×10^26 electrons

And, Since 1 mole electron= 6.02×10^23 electrons

So No. Of moles of electron in 6.04×10^26 electron

= {6.04×10^26}÷{6.02×10^23} = 1000 moles electron

Here, 0.55 g electron contains 1000 moles of electron.
