What is the actual volume occupied by water molecules present in `20 cm^(3)` of water ?

A

`20 cm^(3)`

B

`10 cm^(3)`

C

`40 cm^(3)`

D

`24.89 cm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Half of the volume occupied in water is empty or unoccpied. Therefore, `10 cm^(3)` of the actual volume is occupied by water molecules present in `20 cm^(3)` of water.
