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 .
27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
'e' = the energy equivalent of a sample of mass 'm' = the mass of the sample of mass 'c' = the speed of light
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
Aerogel is 39 times more insulating than the best fiberglass ever made.
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
7.48
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
The answer depends on sample of WHAT!
NO
The volume and the mass of sample both depend on the size of the sample.A small sample has small volume and small mass, a big sample has big volumeand big mass. But the ratio of mass to volume is constant for a pure sample ofa substance, no matter what size the sample is. That ratio is called the densityof the substance.
Mass is an extensive property, which depends only on the amount of matter in the sample, not on the composition of the sample.
The amount and the mass are directly proportional. Halving the amount halves the mass, and vice versa.
What is the mass of that compound? We calculated the mass of the sample.
27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
'e' = the energy equivalent of a sample of mass 'm' = the mass of the sample of mass 'c' = the speed of light
regular (silica) aerogel is not lighter than air but SEAgel is a form of aerogel that is lighter than air
Density of a substance = (mass of a sample of it)/(volume of the same sample)
