Dose - Balloons of Nitrous Oxide From a 20lb Tank?

[shortyg]

Hi i have a question as to the amount of n2o you get out of a 20lb tank



i want to know very very approximatly how many balloons(regular balloons not the humongous ones) a 20lb n2o tank will fill??



i understand that it greatly varies beacuse of a number of reasons, but all i would like is a ballpark number...



any comments would be appericated

thank ahead of time

I was going to get an 11lb tank and I somehow worked out that it was the equivalent of about 650 N2O chargers. Therefore a 20lb tank should be enough for about 1200/1300 balloons. Edited by: psychedelaholic

I would have an easier time calculating this if you could please provide the information on what the pressure is inside the tank and the vollume inside the tank. I'm not familiar with what 20lbs refers to: I suppose it means the entire weight of the N2O contained inside the tank.

Here, I'm attempting this calculation with PV=nRT

Pressure = 1 ATM (outside the tank, used as a reference point)
Volume = Litres of N2O (will determine this as # of hits. 1 hit assumed to be 2L)
n = mols of N2O
R = constant value (as using Atmospheres [ATM] will use value .0821)
T = Temperature (will assume that ambient temp of N2O in a balloon out of it's pressurized state is 283 degrees Kelvin [10 degrees celcius])

so most importantly is calculating n.

20lbs = 44kg
44kg = 44000g
molar mass of N2O is 44g/mol
44000g = 1000mol N2O

PV=nRT

1xV = 1000x.0821x283

V = 1000x.0821x283

V = 82.1x283

V = 23234.3L

so divide that in half to determine the # of "hits" or "balloons"

and I'll assume that gets us in the area of 12,000 hits.

Yes, I like chemistry a lot. Yes, I have taken advanced college level chemistry courses. Yes, PV=nRT is my favorite equation. Yes, this is somewhat rough and I may have made some errors, but from memory I believe I am using the correct values and constants.

And a resounding YES for a long time N2O has been my Drug of Choice, but my fear of having gained tolerance of the substance has caused me to abstain from use. But it's a wonderful thing, Nitrous.

Does one build tolerance to nitrous?
How do you get rid of the tolerance if you build it up?

Thanks
