At 900 K the following reaction has Kp=0.345:

2SO2(g)+O2(g)⇌2SO3(g)

In an equilibrium mixture, the partial pressures of SO2 and O2 are 0.120 atm and 0.470 atm, respectively.

What is the equilibrium partial pressure of SO3 in the mixture?

Express the pressure in atmospheres to three significant digits.
