If the intermolecules forces vanish away, the volume occupied by the molecules contained in `4.5 kg` water at stantard temperature and pressure will be given by

Options

A. `5.6m^(3)`
B. `4.5m^(3)`
C. `11.2m^(3)`
D. `5.6 L`

Answer

A

Explanation

If internmolecular forces vanish aqay, the liquid will convert into vapours.
Molecullar mass of water vapours
`=18g =18xx10^(-3)kg`
So,`18xx10^(-3)kg` of water vapour will occupy `22400 m^(3)` then, 4.5 kg of water vapour will occupy
`(22.4xx10^(-3))/(18xx106(-3))xx4.5=5.6 m^(3)`
