At 550 K, the KcK_c for the following reaction is 10410^4 mol−1^{-1} L.

X(g)+Y(g)⇌Z(g)\text{X}(g) + \text{Y}(g) \rightleftharpoons \text{Z}(g)

At equilibrium, it was observed that [X]=[Y]=[Z][\text{X}] = [\text{Y}] = [\text{Z}]. What is the value of [Z][\text{Z}] (in mol L−1^{-1}) at equilibrium?
