Avagadro's Law and Number

[CJCT927]

Okay, so I get the general idea of this theory: that equal volumes of gases have equal number of molecules.

 

Now, I have to do a presentation in IPS, and I plan on doing a PowerPoint on it, but I was wondering if anyone had any ideas for something to go along with it ... an experiment, a model, or maybe some kind of demonstration.

 

Anyone got any ideas?

 

Thanks

perfect gas equations is a good start. thats how that law is derived. though with the compressibility factor it skews it though,

Check out Eric Rogers, a great presenter at Princeton some years ago. I think any demo might take a lot of equipment and time.

take equi-molar amounts of different chems and then decompose them to a gas, say just enough to fill a gas syringe.

and then test the gases.

 

Hydrogen and Oxygen are simple enough to make and test, Zinc in HCl, and thermal decomp of KCLO3 respectively.

 

Chlorine would be another good one, and you can show it`s 17x the weight of H2, as well as being easy to test (blow it over some Red Phos).
