How many times faster helium diffuses than oxygen at room temperature calculate?

He molar mass = 4 g/molO2 molar mass = 32 g/mol
Rate of diffusion is inversely related to the square root of the molar mass.
√4 = 2
√32 = 5.7
5.7/2 = 2.8
So, He diffuses about 2.8 times faster than oxygen.

This is incorrect. The rate of diffusion is inversely related to the square root of the molar mass. The correct answer would be that helium diffuses about 2.8 x faster than oxygen.

Why hydrogen diffuses four times more than helium?
because the mass of hydrogen is less than that of helium
How would 10g of helium gas be diffrent than 10g of helium contained in a sealed jar?
Helium is helium. Storing it is difficult as it diffuses through many substances.
Does helium come out of a balloon faster than air?
Yes. The reasons are helium is monoatomicand light and therefore at a particular temperature the helium atoms move faster and can diffuse out quicker than the larger molecules N2, O2 in an air filled balloon. (This is Grahams Law of gaseous effusion in practise)Gases are diffusing through theballoon membrane in both directions- the pressure difference is not really that great after all you can inflate a balloon using only lung power.Fill a balloon with a gas such as SF6 then it will inflateas the lighter faster moving air diffuse in at a higher rate than SF6 diffuses out
Is helium a liquid at room temperature?
what is the density of helium at room temperature?
How does helium behave?
helium behaves by helping to blow thing up nd lainch things
Does hcl gas move faster than helium?
No, at the same temperature helium moves faster as it has a lower mass.
Which gas will diffuse faster methane or carbon dioxide?
Helium diffuses twice faster as Methane does.
Will you fly if you inhale helium?
more importantly are you thick, it doesnt, helium diffuses through us
Do helium or argon gases move faster?
At the same temperature, helium gas will move faster due to its lower atomic weight. Helium has an atomic weight of 4g/ mol, while argon has an atomic weight of 39.95g/ mol.
How do helium balloons fall?
Helium diffuses through te balloon skin, out of the balloon, and its bouyancy therefore decreases.
How does the rate of effusion of sulfur dioxide compare to that of helium?
Sulfur dioxide diffuses at one-quarter the rate of helium
Why hydrogen diffuses four times more than helium?
because the mass of hydrogen is less than that of helium
What has a higher velocity helium or oxygen?
At the same temperature and prssure in a gas the helium atoms will on average move faster than the O2 molecules.
