My answer was 0.213 and was wrong.

The equilibrium reaction is shown below. At a specific temperature, the partial pressure of NH3 at equilibrium is measured to be 0.349 atm and the partial pressure of N2 at equilibrium is measured to be 0.295atm. The total pressure in the flask at equilibrium is 1.89atm. What is Kp ? 3H2(g)+N2(g)=2NH3(g) Your answer should have 3 significant figures. Your
