Is air matter ? SCI8

I think air is matter, because it's made from something. Such as Oxygen we breath everyday and it is air, we can't grab it however, we can mass it. For example: We put air in a balloon and it becomes like increase a little weight like 3 grams. So air has mass, and for volume, the volume of air is always different, because when we put air in balloon it becomes circle and for box it becomes squre. When we put some chemical substance it can become oxygen and something else about airs.
