Ok, now I am getting even more curious,

Do you happen to know the volume of 2 mols of CO2? How about the
volume
of single bubble from a 1/4" (standard) air line?


Well, any ideal gas will have a volume of 22.4 L/mol at 298 Kelvin (25
degrees Celcius) so 44.8 L for 2 mol CO2

Given the example with 200 g sugar and 2.2203 mol CO2 it would give 2.2203
mol * 22.4 L/mol = 49.734 L from 200g sugar at 1 bar.


The exact formula is the ideal gas law: pV=nrT where p=pressure, V=volume,
n=mol gas, r=gas constant and T=temperature in Kelvin. At p=1 bar this gives
V=nrT


I can't find my maths book so I cant remember how to calculate the volume of
a bubble or a ball if we assume that a bubble is ball shaped, it's not but I
think it's close enough :-)


Does anybody remember this or have a old maths book handy?


Regards

Morten
