The number of water molecules in one litre of water is:

A

18

B

`18 xx 1000`

C

`6.022 xx 10^(23)`

D

`3.3 xx 10^(25)`

Text Solution

Verified by Experts

The correct Answer is:
D
The water has a molecular weight of 18. One litre of water has 1000 grams. The number of moles is 1000/18= 55.556 moles. The number of molecules is therefore- `6.022 xx 10^(23) xx 55.556`
`=3.346 xx 10^(25)` molecules
