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?
Aerogel can potentially provide some insulation or buoyancy when used on top of radon gas, but the suitability of aerogel to fully support or float on radon gas would depend on various factors like the density and concentration of the radon gas. Generally, aerogel is very lightweight and has low density, which might make it (theoretically) possible for it to float on radon gas under certain conditions.
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.
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 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.
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.
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 happens to the direction of a light wave when it passes from a less dense medium such as air into s more dense medium such as glass?
When a light wave passes from a less dense to a more dense medium, such as air to glass, it slows down and bends towards the normal (an imaginary line perpendicular to the surface). This phenomenon is known as refraction. The change in speed and direction of the light wave is due to the change in the medium's refractive index.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
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 the earth moon less dense than mercury?
Yes, the Earth's moon is less dense than Mercury. Mercury is one of the densest planets in the solar system, with a density about 5.4 times that of water, whereas the Moon has a density about 3.3 times that of water.
