What is the specific gravity of H2O?

Answer 1

Specific gravity, also known as relative density of water is 1. Actually density of water is SI system of units is 1000 kg/m3.

Relative density of any substance is the ratio of its density to that of water. So Mercury having 13600 kg / m3 as density would have 13600/1000 = 13.6 as relative density or specific gravity of mercury

Answer 2

It is a measure of the density, or mass per unit volume of a substance.

The specific gravity of every liquid is relative to the density of pure water = 1.0 kilogram/liter

A liquid having a specific gravity of 1.3 (methylene chloride) is more dense than water and will sink whereas a liquid with specific gravity 0.8 (oil) is less dense and will float.

Answer 3

Very nearly 1.

"Specific gravity" is the ratio of the density of a substance to the density of some other reference substance. It's a deprecated term nowadays; it's far better to just give the density directly, especially since by far the most common reference substance is water at 4 degrees Celcius, which happens to have a density of almost exactly 1 gram per milliliter, meaning that the if you limit yourself to one or two decimal places, the old "specific gravity" has numerically the same value as the density measured in grams per milliliter (or kilograms per liter).

Since the referent is water, asking for the specific gravity of water is basically saying "what is the ratio of the density of water to the density of water". It shouldn't be surprising that this number will be very close to one (the reason it's not exactly 1 is that the density varies with temperature, so if the two water samples you're comparing are not at the same temperature they won't have exactly the same density).

Answer 4

Water has a density of 1000 kg/m^3. Blood has a density of 1060 kg/m^3. Specific gravity is a dimensionless quantity. Therefore, blood has a specific gravity of 1.060.

Answer 5

Think of it as relative density (relative to water density = 1g / cm3)

So if sg is say 1.8 then density is 1.8 times that of water = 1.8 * 1 = 1.8 g / cm3

Answer 6

The density of liquid hydrogen is only 70.99 g/L (at 20 K), a specific gravity of just 0.07099, liquid hydrogen requires cryogenic storage to remain at this temperature.

Answer 7

The density (not specific gravity) of water at 20 0C is 0,998 207 1 g/mL.

Answer 8

Density = Mass/Volume

The density of natural gas (CH4) is approx. 800 g/m3.

Answer 9

That varies widely between different solids. For example, ice has a density less than water (that is, slightly less than 1 gram/cm3), while some metals have a density of more than 20.

Answer 10

specific gravity of Hydrogen is 0.070
