Question

The rate of diffusion of hydrogen gas is

• A. 1.4 times to $V_{2}$ gas
• B. Same as $V_{1}$ gas
• C. 5 times to $V_{1}$ gas
• D. 2 times to $V_{2}$ gas

Answer 1

Answer: (A)

1.4 times to $V_{2}$ gas

Answer 2

We know that molecular mass of hydrogen $H_{2}O$ and that of helium $100kPa$, we also know that Graham's law of diffusion $N_{2}$; $320kPa$
