Gas Laws & Ideal Gas Equation

The volume occupied by the molecules contained in 4.5 kg water at STP, if the intermolecular forces vanish away is

Show answer and solution

Answer: (d)

With no intermolecular forces the water behaves as an ideal gas: 1 mol occupies $22.4$ L at STP.
Moles $= \dfrac{4500}{18} = 250$ mol
$V = 250 \times 22.4 \text{ L} = 5600 \text{ L} = 5.6$ m $^3$
So the answer is (d) $5.6$ m $^3$ .
