please help!!

Nickel carbonyl decomposes to form nickel and carbon monoxide, like this: Nifco),(0) --Ni(s)+4C0() At a certain temperature, a chemist finds that a 9,5 L reaction vessel containing a mixture of nickel carbonyl, nickel, and carbon monoxide at equilibrium has the following composition: compound amount NI(CO), 0.280 8 Ni 755 1.318 Calculate the value of the equilibrium constant K for this reaction. Round your answer to 2 significant digits
