Aerogels are a diverse class of materials which can be composed of many different substances. The lowest density aerogels that have ever been produced were silica aerogels about 0.0011 g/cm3 in density, making them about 2002 times lower density than fused silica, a high-purity form of glass which has a density of 2.203 g/cm3. This is the most useful direct comparison since the composition of silica aerogels and fused silica are the most alike. In comparison to common soda-lime glass, which contains elements other than silicon, oxygen, and hydrogen and has a density of about 2.52 g/cm3, these ultralow density aerogels are 2291 times lower density. Typically, silica aerogels and non-silica aerogels range from about 0.01 g/cm3 to 0.5 g/cm3 in density, so a useful range to report would be "between 5 to 250 times lower in density than common soda-lime glass, and as low as 2290 times for the lightest aerogels ever produced".

Can aerogel float on radon?
Yes. Aerogel is less dense than radon. I think it's also less dense than xenon. For a while I wondered about it too, but yes, a solid can float on a gas.
What are some of the least dense materials?
Pentane is 0.626 g/cm^3 at 25 C and one atmosphere. Hydrogen is 0.070 g/cm^3 at -253 C and one atmosphere.Read more: What_is_the_lowest_density_liquid_commonly_availablei did not wright this!
What is less dense glass or water?
Generally, glass is more dense than water. (There are some types of glass which are less dense.) You can demonstrate this by gently placing a glass full of water in the sink or tub; the glass will sink, indicating that glass is more dense than water. If the glass were to float, we would know that the glass were less dense. Try this with plastic cup; the plastic is normally less dense, and will float.
What is a way to see that ice is less dense then liquid water?
Put ice cubes in a glass of water. They will float, indicating that they are less dense than liquid water.
Will borosilicate glass shatter in the oven?
Since its less dense than normal glass, it will shatter or crack easily. If you put it in the oven more than 5 or 6 times it might shatter due to the heat.
What happens to the dirtier of a light wave when it passes from a less dense medium such as air into a more dense medium such as glass?
The answer depends on what on earth you mean by the "dirtier" of a wave.
If a glass block had two or three chips what would happen to the density measurement?
The density of the glass has not changed, but since air is less dense than glass, the density of the block has decreased.
What is least dense cork or lead?
Cork is less dense than water because it floats. Both glass and Mercury (a metal) are denser than water.
Is ice less dense or more dense than water?
no
Why do ice cubes always float a the top of the glass of water?
Ice is less dense than water and will float on water.
Is a plastic cup lighter than a glass cup?
Plastic is less dense than glass, so normally a plastic cup is considerably lighter than a glass cup, although in theory a very small glass cup could weigh less than a very large plastic cup.
When light travels from air into glass the wave speed?
Its speed would decrease upon moving from a less dense to a more dense medium
