\what is the volume at stp of a 125.0 ml of a gas at 1.50 atm and 100 C?
do I use PV=nRT? What does each letter represent? or do I use p1V1=P2V2?

P = pressure
V = volume
n = number of moles
R = the gas constant
T = temperature (always in Kelvin)
p1V1=P2V2 doesn't help with the change in T.
You could use PV = nRT twice, but it's quicker to do this:
(125.0 ml) x (1.50 / 1.00) x (273 / (100 + 273)) = 137.2 ml
