What is the pressure of 4 moles of helium in a 50 liter tank at 308k?
2.02
What is the mass of 1 liter of helium and 1 liter of air?
Around 0.12 percent, it differs in different countries depending on the environment and altitude.
How many grams is 1 Liter of Helium?
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.
Does helium have more density than air?
Yes, all substances have density. Helium has a density of 0.1664 g/liter at 20°C and one atmosphere of pressure.
Assume you fill a 22.4 liter balloon with helium gas how much would the gas inside weigh?
22.4 liter of Helium will weight 4.0026 g
How many cubic meters of Helium gas can be received from one liter of liquid Helium?
10^-3
What will be the result if you increase the pressure on one liter of nitrogen?
If you increase pressure on one liter of nitrogen the volume occupied by that liter of gas will decrease.
What would be the volume of 1 liter helium gas if transferred to liquid helium?
2.5 liters. The gas will fill whatever volume you put it in, no matter what (as long as it remains a gas and not a liquid). The only thing that will change is the pressure and/or temperature of the gas when making the transfer.
What is the density of helium per liter?
According to Wikipedia, the density of helium is 0.1786 g/L(at 0 °C, 101.325 kPa).
Explain how you can find the volume of helium gas in a one liter tank?
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.
If 3750 liter of air must be compressed into a 26 liter tank what will be the final pressure of the air in the tank?
assume that the air is originally at atmospheric pressure
What makes helium float?
Helium-filled objects "float" in most substances that aren't primarily hydrogen or helium because of it's less dense. Helium has a weight of 0.1785 grams per liter. Nitrogen, on the other hand, which makes up 80% of the air we breathe, weighs 1.2506 grams per liter. Things that are lighter over the same surface area are more buoyant.However, helium isn't the lightest element. Hydrogen, weighing a mere 0.08988 grams per liter, is. The reason hydrogen isn't used as commonly as helium to fill things is because of the high flammability of hydrogen, with a small spark causing a hypothetical hydrogen balloon to explode.
