If all intermolecular attractions were removed, what volume would be occupied by the molecules present in 4.5 g of water at standard temperature and pressure?
- 5.6 litre
- 4.5 litre
- 11.2 litre
- 6.5 litre
Correct answer: 5.6 litre
Solution
If intermolecular attractions vanish the molecules behave as an ideal gas at STP. 4.5 g water = 0.25 mol, occupying 0.25*22.4 = 5.6 litre.
