I suppose one could measure the circumference etc, and find the volume.
Then, with the volume, find out how many moles of He there would be in it, and then find the weight...
The problem is, I have neither a baloon, or a measuring apparatus.
I'm just hoping someone who already knows what the answer is can tell me.

I was just going to assume the balloon is a sphere...

If you do it your way, you need to take into account that the more you blow a balloon up, the higher the pressure that the sides of the balloon will exert on the helium =) This would compress the gas, and that would mean the gas is denser.

did some google research and an "adult baloon" called jumbo has a filling volume of 160 cube meters. Considering that pressure would be 1 atm and temperature 25 C, 7143 moles of He would be needed, so the helium alone would weigth 28,57kg.

They are lighter than air, so I am not sure it actually possible to weigh them. If you have an accurate count of the Helium molecules, I suppose it is possible. Volume would depend on the size of the balloon. I suppose you could immerse them in water to get that.

Good Question, Id like to know myself. How would you go about weighing something like that?
