The number of molecules in 1.0 mole of H2O is _ as in one mole of O2

The same.

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules.

This implies that 1 mole of H2O contains 6.02×10²³ molecules and also, 1 mole of O2 contains 6.02×10²³.

From the above illustration, we can see that 1 mole of H2O and 1 mole of O2 contains 6.02×10²³ molecules respectively.

Therefore, the number of molecules in 1 mole of H2O is the same as in 1 mole of O2.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
