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

Answer

A

Explanation

a. ` mu = ("Mass of water")/("Mol e cular wt. of power") = (4.5 kg)/(18 xx 10^(-3) kg) = 250`
`T = 273 K` and `P = 10^(5) N//m^(2)` (STP)
From `PV = mu RT`,
`implies V = (mu RT)/(P) = (250 xx 8.3 xx 270)/(10^(5)) = 5.66 m^(3)`
