What is the formula for finding the volume taken by a given amount of gas at a certain temperature and pressure? I used to do this all the time in high school chemistry, but now that I need it, I dont' know it! Stay in school!

Just rusty. The formula hasn't changed much.

PV= nRT. P is pressure, V is volume, n is the number of moles (in your problem, 1), R is a gas constant consistent with the other units, and T is an absolute temperature.

I like to use P in atmospheres, V in liters, T in degK. For that combo, R= 0.082 L-atm/oK-mole.
If you have different units, like Pascal or mm Hg, you will need a different "R"

It is the idea gas law

PV = nRT

where
P = pressure
V = volume of the gas
n = the number of moles of gas
R = the idea gas law constant
T = Temp

For STP one mole of gas occupies about 22 L

WIth a vacuum air purifier? Or in facet of a vacuum. A vacuum is the perfect concern, i'm particular the the boiling temperature of water would decrease yet.....70 tiers F is fantastically low. 212 F is Boiling temps. submit to in techniques that a vaccum will lack gadgets that mirror warmth components, my wager would be No!
