The volume occupied by the molecules contained in 4 . 5   kg water at STP, if the intermolecular forces vanish away is

Options

  1. A5 . 6 × 10 3   m 3
  2. B5 . 6 × 10 - 3   m 3
  3. C5 . 6   m 3
  4. D5 . 6 × 10 6   m 3

Correct answer

C. 5 . 6   m 3

Step-by-step solution

Molecular mass of water is 18   g   mol - 1 Therefore, number of moles in 4 . 5   kg of water will be, n = 4500 18 = 250 Volume occupied by one mole of gas at STP is 22 . 4 Litre Therefore, volume occupied by 250   mol of water will be V = 22 . 4 × 10 - 3 × 250 ⇒     V = 5 . 6   m 3
