What is the pressure (in torr) inside a 2.0 liter flask at 26°C and 27.2 grams of oxygen gas?



Answer:
We use the equation pV = n RT
molar mass O2 = 32 g/mol
n = moles O2 = 27.2 / 32 = 0.85
T = 26 + 273 = 299 K

p = nRT / V = 0.85 x 0.0821 x 299 / 2.0 = 10.4 atm

Since 1 atm = 760 torr
10.4 x 760 = 7929 torr
