Q. 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) $5.6 \times 10^6\ m^3$
C) $5.6 \times 10^3\ m^3$
D) $5.6 \times 10^{-3}\ m^3$
Explanation
[Solution] Without intermolecular forces water behaves as an ideal gas: n = 4500/18 = 250 mol; V = 250 × 22.4 L = 5600 L = 5.6 $m^3$. Answer (1).
