Question

*The rate of diffusion of hydrogen gas is _____ times that of oxygen gas.*

1️⃣ 2
2️⃣ 4
3️⃣ 1/4
4️⃣ 1/2​

Answer 1

Answer:

(2) 4

Explanation:

Hydrogen/Oxygen=(32/2).5=4

Answer 2

The rate of diffusion of hydrogen gas is 4 times that of oxygen gas.

Graham's Law

• A gaseous substance's rate of effusion is inversely related to its molar mass squared.
• Graham's law says that the ratio of the rates of diffusion or effusion of two gases is equal to the square root of the inverse ratio of their molar masses.
• Hydrogen has a molar mass of 2. 0 g/mol, while oxygen has a molar mass of 32.0 g/mol. Due to the fact that rate is inversely related to molar mass, hydrogen has a four-fold higher rate of diffusion than oxygen

​As a result, hydrogen gas diffuses four times quicker than oxygen gas.
