Helium has a density of 0.1785 kg/m3 = 0.1785 g/L = 0.0001785 kg/dm3 = 0.0001785 kg/L = 0.0001785 g/cm3 = 0.0001785 g/mL.
Density at stp (0 °C and 101.325 kPa): 0.1786 g/L
He: 4.00g/1 mol x 1 mol/22.4 L = 0.178 g/L
Its equal the the density of water. Its very dangerous in some parts of the world because people mix it up with water and explode drinking it.
Its density is 0.1786 g/L at 0 °C and 101.325 kPa
Helium is lighter (less dense) than oxygen & nitrogen.
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
Helium has a lower density than air.
No, relative density is relative to water. Therefore, oil with a relative density of 0.9 is 90% the density of water. Which is why oil floats on top of water. Put both in a glass to see.
Approximately 4.01
the relation between relative density and density is that relative density of a substance is its density itself without its unit.
If the question is regarding helium's density, helium has a very low density as its natural state is as a gas. It's density is 0.0001785 grams per cubic centimeter.

Relative density is determined by the ratio of the density of a substance to the density of a reference substance.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
relative density is related to the density of water. i.e. a relative density of 19.3 means that it has a density 19.3 times the density of water. The density of water is 1g/ml therefore the density of gold is 19.3g/ml
Helium is lighter (less dense) than oxygen & nitrogen.
There is one thing that is relative to both helium and hydrogen. Both of these are a type of chemical.
Helium
The density of helium is less than that of air. Due to this reason, balloons filled with helium will float in air.
In SI system, unit of density is kg/m3 But no unit for relative density as it is the ratio of density of the material to that of water
