The volume occupied by the molecules contained in \( 4.5\text{ kg} \) water at STP, if the intermolecular forces vanish away is:

  1. A
    \( 5.6 \times 10^{-3}\text{ m}^3 \)
  2. B
    \( 5.6\text{ m}^3 \)
  3. C
    \( 5.6 \times 10^6\text{ m}^3 \)
  4. D
    \( 5.6 \times 10^3\text{ m}^3 \)
View Answer & Solution

Correct answer · Option B

\( 5.6\text{ m}^3 \)

Explanation

Number of moles \( n = \frac{4.5 \times 10^3\text{ g}}{18\text{ g/mol}} = 250\text{ moles} \). At STP, volume \( V = n \times 22.4\text{ L} = 250 \times 22.4 \times 10^{-3}\text{ m}^3 = 5.6\text{ m}^3 \).
