what is standard density?

Answer 1

The density under S.T.P. conditions (standard temperature and pressure; 0 degrees Celsius temperature and 760 mm Hg pressure).

Answer 2

Density at 4 deg celsius under 760 mm Hg.
Bye the way, the standard temp is 298 or 300 Kelvin ( 25 or 27 degree celsius) depending on various works.

Answer 3

In physics, usually the density of water at the ice point (0°C), 0.99984 g cm -3 ; or the maximum density of water (at 4°C), 0.99997 g cm -3 .

Answer 4

Density, or volumic mass (ISO 31), is a measure of mass per unit volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have more mass than an equal-sized object made from some less dense substance (such as aluminium). Is called standard density!!!!

Answer 5

First answer is correct but he did not mentioned that Specific gravity of 1, is numerically correct Standard density at STP.

Also water has to be distilled water.
