would a container with a vacuum in it float?

Theoretically, if you have one solid sphere of glass, one hollow sphere with air in it and one hollow sphere with a perfect vacuum inside. would the  one with a vacuum float better than the one with air? what would happen?

Also say you had a zeppelin that could keep its shape despite there being vaccum inside it, would it float? can a container float in air if there is vacuum inside, it is light enough and strong enough to not implode?

Yes. If you could create a light container with a vacuum inside it that won't collapse under atmospheric pressure, it will experience more buoyancy than helium or hydrogen filled things do. It would be very hard to create that type of container though.
