हिन्दीThe volume occupied by the molecules contained in \( 4.5\text{ kg} \) water at STP, if the intermolecular forces vanish away is:
Correct answer · Option 2
\( 5.6\text{ m}^3 \)
Explanation
Number of moles \( n = \frac{4.5 \times 10^3\text{ g}}{18\text{ g/mol}} = 250\text{ moles} \). At STP, volume \( V = n \times 22.4\text{ L} = 250 \times 22.4 \times 10^{-3}\text{ m}^3 = 5.6\text{ m}^3 \).
