An 8.00-g sample of SO3 was placed in an evacuated container, where it decomposed at 600.oC according

Question:

An 8.00-g sample of SO3 was placed in an evacuated container, where it decomposed at 600.oC according to the following reaction:
SO3(g) ⇌ SO2(g) ⇌ ½O2(g)
At equilibrium the total pressure and the density of the gaseous mixture were 1.80 atm and 1.60 g/ L, respectively. Calculate Kp for this reaction.
