What is the molecular mass of a gas that diffuses 1 50 as fast as hydrogen?

By Graham’s Law, 1 / 50 = square root (2.02 / x) = molecular weight of 5050. 3. Two porous containers are filled with hydrogen and neon respectively. Under identical conditions, 2/3 of the hydrogen escapes in 6 hours.

What is the molecular weight of gas which diffuses 1/6 as fast as hydrogen?

Answer: The molar mas of unknown gas is 72 g/mol.

How much faster does hydrogen gas diffuse than Sulphur dioxide?

Problem #5: How much faster does hydrogen escape through a porous container than sulfur dioxide? Hydrogen gas effuses 5.637 times as fast as SO2 gas does.

What is Graham’s Law of Diffusion and explain?

Graham’s law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Therefore, the rates of diffusion of different gases are inversely proportional to the square roots of their mass densities.

What is the ratio of diffusion rate of oxygen to hydrogen?

$ 1:4 $
Rate of diffusion of a gas is inversely related to the square root of molar mass of a gas. Therefore, the ratio of diffusion rate of oxygen to hydrogen is $ 1:4 $ .

Is the molar mass of hydrogen 1 or 2?

Therefore, a hydrogen molecule’s mass is 2 amu, oxygen is 32 amu and nitrogen is 28 amu. Now let’s talk about what is meant by a MOLE of a substance…also refered to as a gram-mole.

What is the molar mass of 2 hydrogen?

To get the molar mass of water, you would add up the molar masses of 2 hydrogens (2 x 1.01 g) and 1 oxygen (1 x 16 g). The molar mass of water would then be 18.016 g/mole.

Which gas diffuses the fastest?

Explanation: The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium.

Which gas diffuses faster hydrogen or helium?

Graham’s law of diffusion states that the rate of diffusion is INVERSELY proportional to the square root of the molecular masses of each gas…. And thus dihydrogen will diffuse approx. 1.4 times faster than the more massive helium….
