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

According to google the volume of a sphere is 4/3 * pi * r^3.
