At 250 degrees celsius, PCl5 (equilibrium arrow) PCl3+Cl2 has an equilibrium constant Kc=1.80. iF 0.500 MOL OF PCl5 is placed in 2 L container, what will be the equilibrium concentration of Cl2?

Hey there! Your ICE chart is correct but I think you made a mistake in your equilibrium equation. Here we needed to do a quadratic formula :(

If you look at my answer, you see that one of the x's is a negative, that can't be right, so it has to be 0.225. That would be the concentration of Cl2 since its x. Hope this helps.
