Answer 1

Answer:

4. option

Explanation:

As we know that

1 mole of any substance is equal to 22.4 L which is equal to 6.022*10^23 particles.

Since water , H2O and ice mean the same and have the same molecular formula

Therefore 15 L of all of them contains the same number of moles and same number of molecules.

Hope this helps.
