Assume that a bicycle tire with an internral volume of 1.50 liters contains 0.405 mole of air. The tire will burst if the internal pressure is 7.25 atm. What is the temperature of the air in the tire if a blowout occurs?

PV = nRT
You have all except T. Solve for T in Kelvin. 
So the equation would be:
PV/nR = T 
yes

Just to make sure:
(7.25atm)(1.50 L)/(0.405 mol)(0.0821 L atm/l mol) = T
Final answer: 327 K 
looks ok to me.
