Question

The total number of electrons present in 18ml of water is:

Answer 1

1000 ml water = 1000 gm water

So 18 ml water = 18 gm water

Mole = 18/18 =1 mol

( molecular weight of water =18)

In 1 atom of water total electrons are 10

So in 1mol atom electrons =?

=6.022 x 10^23 x 10

=6.022 x 10^24
