Question

The number of electrons present in 90ml of water is

Answer 1

Answer:

please mark it brainliest

Explanation:

Density of water= 1gm/cm³ 1g/ml=18gm/18mlSo, 1mole/18gmNow 1molecule of H2O will have 10 electrons.....1+1+8Therefore 1 mole of H2O will have 10xNA electrons.. .. So ans is 10NA. Hope it helps you.

Answer 2

Answer:

each molecule of water contains 10 electrons. Thus 6.023 x 10^(23) molecules of water will contain 10 x 6.023 x 10^(23) electrons= 6.023 x 10^(24) electrons.
