Question

The volume occupied by the molecules contained in 4.5 kg water at STP, if the intermolecular forces vanish away is : (A) 5.6 m 3 (B) 5.6 × 106 m 3 (C) 5.6 × 103 m 3 (D) 5.6 × 10-3 m 3

V = (no. of moles) (22.4 litre) =( text mass / text molar mass )(22.4 × 10-3 m 3. ) =(4.5 × 103/18) × 22.4 × 10-3 m 3 =5.6 m 3

Q. The volume occupied by the molecules contained in $4.5 k g$ water at STP, if the intermolecular forces vanish away is :

$5.6 m^{3}$

$5.6 \times 1 0^{6} m^{3}$

$5.6 \times 1 0^{3} m^{3}$

$5.6 \times 1 0^{- 3} m^{3}$

$V =$ (no. of moles) $(22.4$ litre)
$= \frac{mass}{molar mass} (22.4 \times 1 0^{- 3} m^{3}$ )
$= \frac{4.5 \times 1 0 ^{3}}{18} \times 22.4 \times 1 0^{- 3} m^{3}$
$= 5.6 m^{3}$
