Question

Find the total number of electrons present in 18ml of water

Answer 1

Answer:

Density of water => 1 gm /cm³

1 gm /ml => 18gm /18ml

1 + 1 + 8 = 10

Therefore, one molecule of H20 will have 10 electrons.

10 × NA electrons => 10NA

So we know that there are 10NA electrons present in 18 ml of water.
