Because air has weight, the air inside a baloon is slightly compressed therefore there is more air inside the balloon than outside..otherwise the ballon would not expand...this makes the baloon with air slightly higher.
exception to this would be if air inside the balloon is warmer than outside at the time of filling...warm air is less dense than cold air.and weighs less.
the real answer lays some where in the temp of the air inside to the weight of the air outside the balloon inflated to deflated.

Balloon with air. Due to air buoyancy, the balloon with air will appear lighter.
If you are familiar with some logic, it will always be true that if a=b
therefore a+1>b
Applying the above knowledge:
there must be 2 balloons with equal weight
if you add air to the other, it will be:
weight of the balloon + weight of the air>weight of the balloon

Weigh an empty balloon and then one you blew up. The one filled with air weighs more. If you are talking about a helium filled balloon, then the helium is lighter than aor because it is a very low density gas.

A balloon with air weighs less but has more mass.
