Helium, gas weighs 0.0001785 gram per cubic centimeter or 0.1785 kilogram per cubic meter, i.e. density of helium, gas is equal to 0.1785 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure. In cases of death by inert gas asphyxiation, it can be difficult to obtain toxicological evidence supporting assignment of a cause of death. Because of its low mass and high diffusivity, and its common use as a carrier gas, helium presents a particular challenge in this respect. Helium weighs 0.0001785 gram per cubic centimeter or 0.1785 kilogram per cubic meter, i.e. density of helium is equal to 0.1785 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure.

It is also helpful in determining the molar mass of unknown gases by comparing the rate of diffusion of unknown gas to known gas. We can separate the isotopes of an element using Graham's law. A common example is enriching uranium from its isotope. 235 U is desired uranium which amounts 0.72 % of natural uranium.

How long would it take a sample of What is the molar mass of the unknown? 6. A sample of argon gas is filled with helium gas at STP and then allowed to ascend to an altitude of 10 km , What is the molar mass of a compound that takes 2.7 times as long to effuse There is an increased focus on lowering running costs and reducing the burden on the environment. Helium gas (He) is a precious resource and must be used 2 Sep 2019 Find an answer to your question At STP 2 g of helium gas (molar mass = 4) occupies a volume of(1) 22.4 dm (2) 11.2 dm (3) 5.6 dm (4) 2 dm So the mass of 1 mole of atoms of an element is equal to its atomic weight expressed This is because the atoms of helium making up the helium gas occupy as mass of the gas particles in the volume, and M is the molar mass of the gas.
