What is the mass of a sample aerogel?

Answer 1

That's going to depend on the size of the sample you have. A larger sample

will have more mass than a smaller sample, much like virtually every other

known substance.

Aerogel is a synthetic porous material derived from a gel, in which the liquid

component of the gel has been replaced with a gas. The result is a solid with

extremely low density and thermal conductivity. It is nicknamed frozen smoke,

solid smoke, solid air or blue smoke owing to its translucent nature and the

way light scatters in the material; however, it feels like expanded polystyrene

(styrofoam) to the touch.

Various samples of aerogel may have densities anywhere between 1 mg/cm3

(less dense than air) to 2 mg/cm3 .
