temperature and material of the bottle doesnt matter. I think the question means just the general idea of what weighs more.

say like a 40x50x10 ft classroom and a 20oz bottle of water

Water is approximately one thousand times denser than air.
So the amount of air which would be the same weight as the bottle is only ten bottle diameters wide, ten bottle diameters along, and ten bottle lengths high.
A pretty cramped classrom, I would think. In fact, only about as big as a locker.

The classroom.
Air weighs about 1 kg per cubic metre.
Water weighs 1 kg per litre - a large bottle full.
So the classroom would only need a volume of 1 cubic metre to weigh more, and it will be much larger than this.

What is the bottle made of? How much water will it hold? What is the temperature of the water? What is the barometric pressure? What is the temperature of the air?

well, it depends if your expected to lift up the classroom.
but if you mean bare air and bare water, water is heavier.
