Expert Answer:

Density of water is 1000 g/L.

The gram molecular mass of water is 18.02.

So, number of moles in 1 litre = 1000 / 18.02 = 55.5 moles.

1 mole of water = 6.022 x 1023 molecules of water,

So 55.5 moles of water = 55.5 x 6.022 x 1023 = 3.34 x 1025 molecules of water.

3.34 x 1025 molecules of water = 1 litre,

1 molecules of water = 1 /3.34 x 1025 = 3.0 x 10–24 litre.
