The question seems to be asking about the amount of helium in a liter of gas. One liter of gas is a volume measurement, and it can contain different amounts of helium depending on the mixture. If you're asking about pure helium, one liter will contain one liter of helium gas at standard temperature and pressure. If it's a mixture, the helium content would be specified as a percentage or in terms of partial pressure.
Approximately 740 cubic meters of helium gas can be generated from one liter of liquid helium when it evaporates. Helium gas expands greatly when transitioning from liquid to gas form due to its low boiling point and high expansion ratio.
you need to state the temperature and pressure. The ideal gas law shows that pressure is inversely proportional to volume and temp is proportionally to volume, so volume, and thus, concentration of molecules, thus weight would be different depending on the temperature and pressure.
As of September 2021, the current cost of liquid helium is approximately 4 per liter.
Better check on that again, helium is lighter than air and the specific gravity of air is approximately 1.3 milligrams per cubic centimeter. Water weighs much more than air, 1 gram per cubic centimeter.
The mass of 1 liter of helium is approximately 0.1785 grams, while the mass of 1 liter of air (at sea level) is around 1.225 grams. Helium is lighter than air because its atomic mass is lower than the average molecular weight of air, which is mainly composed of nitrogen and oxygen.
The weight of the helium gas inside the balloon can be calculated using its molar mass, the Ideal Gas Law, and the given volume. Assuming standard conditions, helium gas has a molar mass of 4 grams per mole. Thus, a 22.4 liter balloon filled with helium gas would weigh approximately 32 grams.
The density of helium gas at 25 degrees Celsius is approximately 0.1785 grams per liter.
According to Wikipedia, the density of helium is 0.1786 g/L(at 0 °C, 101.325 kPa).
Helium is significantly less dense than both oxygen and nitrogen, the major components of air. The density of helium is about 0.1785 grams per liter, while nitrogen is approximately 1.2506 grams per liter and oxygen around 1.429 grams per liter. This difference in density is why helium-filled balloons rise in the atmosphere; they are buoyant in the denser air composed mainly of nitrogen and oxygen.
You don't have to find the volume ! If gas is put into a closed container, it fills it. The volume of gas in a one liter tank is one liter.
22.4 liters contain 4.0026 g So, 2 liter will contain 0.36 g
The density of helium at room temperature and pressure is approximately 0.1785 grams per liter.
