It depends on the airplane you want to buy. A Boeing 747 can cost you millions of dollars.
Airplane? What airplane? My paper airplane wings weigh less than 8 grams.
Paper, because it is much lighter, and a foil airplane will take up much more mass.
Stand on a scale. Figure out how much you weigh. Then pick up the airplane and stand on the scale. Subtract how much you originally weighed, and that is the weight of the airplane.
That question has a varied answer. It depends what type of airplane you're asking about
