Methane is lighter than air, having a specific gravity of 0.554.
Thus a mineral with a specific gravity of 2 weighs twice as much as the same volume of water.
Dolomite has a Mohs hardness of 31/2 to 4 and a specific gravity of 2.85 ± 0.01.
The gas carbon dioxide, which has a density of 1.976 grams per litre under standard conditions, has a specific gravity of 1.53 (= 1.976/1.29).
If fluid intake is stopped for 24 hours, a normal kidney will secrete urine with a specific gravity of at least 1.025.
Metallic berkelium has been prepared; it is electropositive, reactive, and silver-coloured like the other actinoid metals, with a specific gravity of 14.8.
With a specific gravity of about 11.35 grams per cubic centimetre, lead is the densest of the common metals, except for gold; this makes it a good shield against X-rays and gamma radiation.
It is soft to brittle, with a specific gravity of about 0.95 and a melting point of more than 140° F (60° C), and it consists mainly of free cerotic acid and myricin (myricyl palmitate), with some high-carbon paraffins.
Barite (barium sulfate, BaSO4) contains 58.8 % barium and has a specific gravity of (4.2 4.5).
Super plasticizer, that has a specific gravity of 1.01 g/cm3, was used.
Its Mohs hardness is 3.5 and it has a specific gravity of 1.88 1.90 [86, 86].
