Graham’s Law Help
« on: September 03, 2020, 12:59:28 PM »
Suppose 2.20X10-4 moles of nitrogen escape through a hole in 105s. Under the same conditions, how many grams of hydrogen would escape through the same hole in 105 s?

Could someone pls walk me through how you solve this. I don’t understand the relevance of using a ratio

Why don't we start with: what is Graham's Law?

Not enough information. It depends on said hole.

That is, the gas' inertia can limit it speed. Or its viscosity. Or the diffusivity.

You might try to guess what process limits the leak based on the throughput, but it's unsafe.

Come on, on this level we are talking about ideal case, no need to make the problem look more difficult than it is intended to be.
