What is the total mass contained in 2.00 moles of helium?
1 mole of helium weighs 4.0026 g. So 2 mole will weigh 8.0056 g.
How many moles of heLium are contained in 0.255g of helium?
use this formula, n(He)=m(He)/M(molar mass of He) =0.255G/4.OO =0.06375 moles per gram.
A balloon has a volume of 6.3 liters Calculate the mass of helium that it would take to fill the balloon?
To calculate the mass of helium, you would need to know the density of helium (0.1785 g/L at 0°C and 1 atm). You can use the formula: mass = density x volume. In this case, mass = 0.1785 g/L x 6.3 L = 1.125 g.
Why are you running out of helium?
I'm personally not running out of helium. In fact helium is harmful to the human body in large doses. So no helium would not affect me.
A lighted splint is put into a gas jar of helium . what would happen?
the lighted splint would stop burning as Helium does not burn.
How would 10grams of helium be different from that of 10 grams of helium contained in a sealed jar?
If helium used is pure and if there is no electric discharge, then chemically helium in both the cases will be same.
What is the total mass contained in 2.00 moles of helium?
1 mole of helium weighs 4.0026 g. So 2 mole will weigh 8.0056 g.
How much helium is needed to lift 400 pounds?
To lift 400 pounds, you would need approximately 74.3 cubic feet of helium. Helium is lighter than air, so it provides lift when contained in a balloon.

Why would a balloon full with helium explode if left in a hot car?
The heat can cause the air inside the balloon to expand, increasing the pressure beyond what the balloon can handle, leading to an explosion. Helium or not, any sealed container in extreme heat can experience this pressure buildup.
Do they put helium in soccer balls?
No, soccer balls are filled with ordinary air If they were filled with helium, they would float into the skyHelium filled soccer balls would certainly not "fly into the sky"! The difference in mass of an air filled ball and one filled with helium would be but a few grams! But the helium (having a much smaller molecule than those that comprise air) would leak out of the bladder more quickly. In addition Helium is much more expensive than compressed air.
What does it mean when an indictment is sealed and why would a court choose to do so?
When an indictment is sealed, it means that the charges contained within it are kept confidential and not made public. A court may choose to seal an indictment to protect the integrity of an ongoing investigation, prevent the destruction of evidence, or ensure the safety of individuals involved in the case.
