Brief answer: no.
Longer answer: 99% of our water vapor is in the lowest layer of the atmosphere, the troposphere.
If any molecules (which are heavier than plain oxygen (02) because they have an attached hydrogen atom) get into the
stratosphere, they usually get ionized.
So, water vapor is so heavy that 99% of it never makes it as far as the ozone layer.
While your conclusion is correct, your chemistry is way off. Diatomic oxygen(O2), the natural state in which most oxygen exists has a molecular
weight of 31.88 +/- 0.0008 grams/mol.. Water vapor (H2O) has a molecular weight of 15.83 g/mol. So, water vapor is about half the weight of diatomic
oxygen. I'm guessing you got confused about the chemical formula for water and were thinking of HO2, which does exist in the atmosphere as a
hydroperoxl radical, an important atmospheric cleansing agent.
The real reason that water vapor exists in the troposphere and not higher is that the adiabatic lapse rate results in saturation and precipitation
as the air gets cooler. Each pound of dry air today in Miami (60% humidity) can carry 159 grams of water vapor. At 15,000 feet, it is down to about
14 grams water vapor per pound of air.At 39,000 over Miami today, the temperature is -65F. At that temperature the water vapor load carrying ability
is almost 0. At an average, the ozone layer is at about 75,000 feet. So water vapor would condense or freeze and fall to earth long before it gets
