Helpful steps please: A sample of hydrogen chloride gas occupies 0.550L at STP. What is the pressure in atm if the volume is 7.50×10−2L at 20∘C?
(P1V1/T1) = (P2V2/T2)
P1 = 1
V1 = 0.550
T1 = 273
P2 = ?
V2 = 7.50E-2L
T2 = 273 + 20
when I plugged these in I got 0.146 but I'm wrong.

Yes  I figured it out that I had put the volumes in the wrong place. Thanks for the verification.
