Answer:
Scales say “2”. So since a balloon full of air weighs more than the empty balloon – voila: Air has weight! ... And that is because what you measure is not the weight of air – the same volume of air was there before you inflated the balloon anyway. What you weigh is the increase in weight as you compress air.
