Recall that standard temperature and pressure (STP) is defined as 1 atm and 0 ˚C

Recall that the ideal gas law is:

$\overline{){\mathbf{PV}}{\mathbf{=}}{\mathbf{nRT}}}$

where

P = pressure (in atm)           R = gas constant (0.08206 atm • L/mol • K)

V = volume (in L)                 T = temperature (in K)

n = moles of gas
