Discussion Overview

The discussion revolves around identifying which gas among methane, oxygen, nitrogen, and C2H6 diffuses the quickest and the slowest. It involves concepts related to molecular mass and diffusion rates, with participants seeking to apply theoretical knowledge to solve the problem.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant asks which gas would diffuse the quickest and the slowest among the given options.
  • Another participant inquires if the original poster's book or class notes discuss the relationship between molecular mass and diffusion speed.
  • A participant suggests that solving the problem requires an equation that relates molecular mass to diffusion rate and encourages sharing the relevant equation from the original poster's materials.
  • One participant calculates the relative molecular masses of the gases: methane (16), oxygen (32), nitrogen (28), and C2H6 (30), implying that this information could help determine diffusion rates.
  • The same participant notes their inexperience in the subject and invites corrections or clarifications from others.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which gas diffuses the quickest or slowest, and the discussion remains open with multiple viewpoints and calculations presented.

Contextual Notes

The discussion lacks specific equations or detailed steps for calculating diffusion rates, and the implications of molecular mass on diffusion are not fully resolved.

which gas would diffuse the quickest? the slowest? A. methane B. oxygen C. nitrogen D. C2H6

(need to show work to verify!)

Does your book or class notes have anything relating molecular mass and speed or diffusion?
 
yes ...
 
Solving this problem uses an equation that contains molecular mass and the speed, or perhaps diffusion rate.

If you can write the equation from your book/notes here, we could look at it together (rather than me trying to guess in what form your book/notes presents the information :smile: )
 
If you use the relative molecular mass formula, you will find that the relative molecular mass of methane is 16, oxygen is 32, nitrogen is 28 and C2H6 is 30. From these, i think you would know which gas diffuses the fastest and the slowest. Also, if you look at the atomic mass of the elements used to make up the different molecules/compounds, you will also find out how to get the relative molecular mass.

*note: i am quite new to this subject so please feel free to correct me if i am wrong. thank you.
