I love getting emails from people who can actually think critically.
If my Dad weren't retired from Pfizer I'd ask him to bring home
chunks of dry ice for me, surely the best way to introduce pure co2
into a small volume - of course I couldn't do the calculations to
determine just how much I'd be adding!
Here's the "easy" way to remember that relationship:
The molecular weight of the ANY gas (in this case, CO2), expressed in
grams (in this case 12+16+16 = 44, the molecular weights of carbon
and 2 oxygens, respectively) will ALWAYS occupy a space of 22.4
Thus, 44 grams of Dry Ice (solid CO2) will fill an area of 22.4
liters when in the gaseous state.
This relationship is true under conditions called Standard
Temperature and Pressure (STP), which means 0 degrees Celsius and 1
atmosphere of pressure, but is close enough for you to calculate how
much dry ice you would need to fill a specific volume.at room
temperature (about 20 degrees C).
Science lesson over.
