A perfect vacuum has no matter, so it has no mass. Density is mass / volume, so the density would be 0.
subtract 0.0011 from the density in vac to get density in air.

Not necessarily. A vacuum is merely any volume having a density lower than an arbitrary amount.
Density = (mass) divided by (volume)Since the mass of any region of vacuum is zero, the density of vacuum is zero.So the density of any material is greater than the density of vacuum.

That depends on the density of the material. For example, 280,000 gallons of a perfect vacuum have a mass of zero tonnes.That depends on the density of the material.

In vacuum, yes. Otherwise the object with a lower density will fall more slowly.
It means that the speed of light in that medium is the same as in vacuum. This is ALMOST the case for stuff like "air". If you measure closely enough, it is only true for vacuum, all other materials have an optical density > 1.
When you release a gas in a vacuum chamber, it immediately drops to the floor because of its density. _______________________________________________________ I expect that the gas will expand to fill the whole volume of the vacuum chamber.
Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber.
