Yes...
.
Apparent weight is actual weight - buoyant force
.
Buoyant force if the weight of the outside air displaced. So we get:
.
empty balloon (displaces no outside air): apparent weight is only weight of balloon material
.
filled balloon: apparent weight is weight of balloon material + weight of air inside balloon - weight of air displaced by balloon outside (i.e. buoyant force)
.
But the weight of air inside the balloon is identical to the weight of the air displaced outside... and so the apparent weight of the filled balloon is just the weight of the balloon material.
.
So the apparent weight of a filled and empty balloon is the same. Note: this is only true of balloons filled with AIR! If you fill the balloon with helium, or some other gas, the equation changes.
