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

Answer

A

Explanation

If intermolecular forces vanish water behaves as gas .
Number of moles of water = `(4.5 xx 10^(3))/(18) =250`
Total volume of water at `STP`
= `22.4xx250 xx 10^(-3)m^(3)=5.6 m^(3)`
