A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.

Does a balloon full of air weigh more then an empty balloon?
Yes, a balloon full of air will weigh more than an empty balloon because the air inside adds mass to the overall weight.
Does an empty balloon weigh less than a balloon full of air?
Yes, an empty balloon weighs less than a balloon filled with air because the air adds to the overall weight of the balloon.
What happens to balloon after being in the freezer for a few hours?
When a balloon is placed in the freezer, the air inside the balloon will condense and the balloon will shrink. This is because the cold temperature causes the air molecules to lose energy and move closer together. When the balloon is taken out of the freezer and warms up, the air molecules expand and the balloon will gradually return to its original size.
Why is a balloon heavier when it is blown up with air?
This depends on whether you consider what is inside the balloon to be a part of the balloon, since the weight of the balloon skin will remain the same regardless of what is inside it. If, however, you consider the contents of the balloon to constitute a part of the balloon's mass then it will always be heavier when inflated, regardless of the density of the substance with which it is inflated. However, in this case the density of the balloon will fall when inflated if the contents are less dense than the material of the balloon, which is highly likely since the substance would probably be a gas. Therefore the balloon would be heavier but less dense.
Will a charged balloon attrack or repel a full soda can?
A charged balloon will attract a full soda can. The balloon will induce a polarized charge distribution on the can, causing opposite charges to be attracted to each other.
