If you created a vacuum filled air balloon sized ball able to withstand ground level air pressure would it weight heavy or lighter than the air around it?

By definition, anything 'filled with vacuum' would weigh nothing, as a vacuum means an area that contains no matter. Since the balloon would need matter in it to weigh anything, a vacuum balloon would be lighter than the heavier air around it, as air is made of matter.

Does air pressure tell you how heavy air is?
Yes because when when you put a balloon in the air the balloon will tell you if its heavier or lighter.
Why was the airplane harder to invent than the hot air balloon?
The balloon is lighter than air.
How do you deflate a balloon by using a lighter?
The heat from the lighter, when placed on the surface of the stretched surface of the balloon,would melt the plastic of the balloon and allow the air inside the balloon to escape, so deflating the balloon.
Why does a balloon inflate when you add helium gas?
A ballon inflates when you add helium to it for the same reason that it would inflate if you added any other gas. By Boyle's law, increasing the number of atoms of a gas to a constant space must increase the pressure of that gas. That pressure, in a balloon, must balance the force required to stretch the balloon as well as the pressure of the atmosphere pressing in on the balloon. This is not the same as the density of the displaced air. The inflated balloon would have less mass than the volume of air it displaces. This would cause the balloon to be lighter than air, and thus rise. If the elasticity of the balloon were smaller than normal, it would require more helium in a smaller volume. If the elasticity was sufficiently small, the balloon would not be lighter than air.
What makes a child's balloon rise?
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
Why was the airplane harder to invent that the hot air balloon?
Balloon is lighter than air.
Is a balloon lighter than 1 kilogram?
Is a ballon lighter than one kilogram
Will a balloon get bigger with water or air?
With same mass, balloon get bigger with air than water because air is much lighter than water. With same standard volume, balloon get bigger with water than air because air is compressible and it will shrink down little bit from the pressure exerted by balloon wall.
How does the air change as a hot air balloon rises?
As the air in the balloon is heated from the flames, the air becomes lighter. So much lighter than the surrounding air that the balloon eventually rises from the light air in it.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
Why was the caraval an important development of navigation?
They were lighter, faster and can withstand storms.
What fills a helium balloon?
Helium which is a lighter-than-air gas, allowing the balloon to float upwards.
