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

A

18

B

18 `xx` 1000

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
18g = 18mL
`18mL = N_(A)` molecules (`N_(A)` = avogadro.s no.)
` 1000 mL = (N_(A))/(18) xx 1000 = 55.555 N_(A)`
