About 0.075 lbs. per cubic foot, Caculated using the ideal gas law: PV=nRT. Assuming the T=68F (528R) and P=1atm with the MW of air approx. 28.8 lb/lb-mole. The gas constant R, using these units is 0.7302. Rearranging the formula to give: mass = MW*(PV/RT)

Umm...technically you can stack spacers, but I don't recommend it and I don't know how many people would. I mean on the street I can assume you will be alright, but once you go offroading and begin to articulate, or take a sharp turn on the road, I don't doubt one of those spaces popping our or at least shifting over.
I wouldn't do it. If you really want more height than just spend the cash and do the OME lift or something. But stacking spacers isn't secure.

How the crap so you figure a front spacer, on TOP of the spring, is going to "pop out or shift over"? There is a bump stop tube that is about 8" long keeping it in place. The rear is a different story, but Teraflex has various height spacers available, as do other manufacturers.
Weld the pucks???
I have to agree, i think if your spacers "pop" out, you seriously have larger issues to be concerned with... Like for instance...
... where did your spring go? 
There are a LOT of people on here who tossed on 3/4" or 1" extra pucks up front to level out the rake from adding bumpers/winches. If you want to be really technical, All the BB/puck lifts are stacking. Remember the rubber isolator...? so what's the difference? None as far as I know.
To the best of my recollection, I have never heard of, or seen one single issue with doing so. I have a set of 3/4" leveling pucks in my garage awaiting installation. When i get some time someday I'll throw them on without a second thought...
...weld the spacers... man that was funny! Thank you for the morning laugh

Stacking coil spacers is not advisable and not a good practice, but it will work to a degree. How long and how well it will work depends on how you drive your Jeep. If you have long long shocks, disconnect the sway bar and flex your suspension to the limit then you are likely to encounter a problem when you least want it. If you rarely flex the suspension or drive only on the road you probably will not have problems.
It's like mounting a 35-37" spare on stock spare carrier. It will work for a while, but your mileage may vary.

The TF spacers are designed to be stacked and they provide a limited amount of lift.
It is not "best practice" to stack spacers to 3"+, particularly from different manufacturers. I believe that is what most object to.
