The answer is in the water vapour.
Vapour has a mass but it doesn't have a weight. Both are measured in kg. Maybe that's it
There's no weight in space but items have the same mass as on earth?
Weight is the force which gravity exerts on a mass. Mass is measured in Kg, weight is measured in Newtons
Try filling a ballon with liquid CO2 vapour. Gravity affects it like anything else. Everything is affected by the density of air and less dense items, like vapours / gases more so. On a set of scales in a vacuum a vapour has weight.
Wee in the kitchen sink? How dare you!
Simples. The fuel when burned is oxidised that takes oxygen. It comes from the atmosphere as the engine sucks in huge quantities (your car does the same). The oxygen and other gasses like Nitrogen are also complexed and create the pollution that is referred to. These gasses actually have mass and their quantity can be described in Kg. So, fuel + atmosphere = total mass of pollutants.
Btw, smoke only rises. When it is less dense than air, usually when it is hot.
