Can anyone convert g/l to volume for me?

[brian92]

I'm looking to convert grams/liter of CO2 in beer to volume. The beer is specified at 6.3 g/l. Anyone know how to convert that to volumes of co2? I did a little research and came up with:

d= (M*p)/(R*T)

d= grams/liter
M = Molecular mass of co2 = 44
p = volume?
R = constant = .0821
T = Temp = 273K (0 celcius)

Is that right? the calc came out to ~3.2

Thanks.

PS - Why do we need to do everything different than the rest of the world? ughh.

1 mole of CO2 is 44g

Therefore, 6.3 grams of CO2 is 0.143 moles of CO2

1 mole of any "ideal gas" is 22.4 liters at standard temp & pressure.

Therefore 0.143 moles of CO2 is 3.2 liters.


So, you are correct -- 3.2 volumes of CO2 per volume of beer.
