shit i haven't taken chemistry since high school sorry mate, i remember how to parts of the problems but not all the way lol

All that shit is pretty easy, you just have to know some formulas and conversions... just took chem in college.

If you're looking for pressure

Always use this formula I have it burned into my head... PV = nRT

So depending what you're looking switch the formula around.

P = nRT/V (Hope you can see how I got that)

P = Prssure
V = Volume
n = molecular weight (But kind of confused they usually give you a specific gas and you find the molar mass of it)
R = .0821 (Never changes R always equals this)
T = Temperature (Take this and add 273 to convert into kelvin if it's not already in kelvin)

1 atm = 760 torr = 760 mm hg
