convert 44.5L of oxygen at 32C and 654mmHg to STP.?
HINT: when STP is stated this gives you a specific temperature and a specific pressure.
Homework help! I'm stuck!

STP conditions are : temperature 0°C and 760mmHg
Use the combined gas equation - temp in K - 32°C = 305K
P1V1/T1 = P2V2/T2
760*V1/273 = 654*44.5/305
V1*760*305 = 273*654*44.5
V1 = (273*654*44.5)/( 760*305)
V1 = 34.3L
Volume at STP = 34.3L
