The number of water molecules in 1L of water is :

A

18

B

`18xx1000`

C

`N_(A)`

D

`55.55 N_(A)`

Text Solution

Verified by Experts

The correct Answer is:
D
`d=M/V` (d = density, M = mass, V = volume)
Since `d=1`
So, `M=V`
18 gm = 18 ml
18 ml `=N_(A)` molecules (`N_(A)=` avogadro's no.)
`1000 ml=N_(A)/18xxx1000=55.555 N_(A)`
