Using the gas laws, calculate the new volume of methane gas at STP, which has escaped from a landfill and been captured at an initial pressure of 1.50atm, an initial volume of 30.0L and an initial temperature of 40.0C.

(P1V1/T1) = (P2V2/T2)
Whatever units you use for the left side use the same units for the right side.
I am only given P1V1T1 though...I am not given the other values..P2V2 and T2
Yes you are, STP means standard temperature and pressure. So P is 1 atm standard, T is 273 K standard and you are to calculate standard V.
