A sample of N2O diffuses at a rate of 82.5 mL/s in a diffusion apparatus. What will be the rate of diffusion in mL/s for Br2 in the same apparatus, assuming ideal gas behavior?

A sample of N₂O diffuses at a rate of 82.5 mL/s in a diffusion apparatus. Using Graham's law of effusion, what will be the rate of diffusion in mL/s of Br₂ in the same apparatus?

A sample of bromine gas requires 84.5 s to effuse from a container. Under identical conditions, how long (in seconds) will it take a sample of neon gas to effuse?

What is the ratio of the effusion rates of hydrogen gas (H2) to krypton gas (Kr) according to Graham's law of effusion?

If NO and NH3 are allowed to effuse through a porous membrane under identical conditions, the rate of effusion for NH3 will be ________ times that of NO.

If NO₂ and NH₃ are allowed to effuse through a porous membrane under identical conditions, the rate of effusion for NH₃ will be how many times that of NO₂?
