The Equilibrium Constant K_c for the Reaction A(g) + B(g) $\degree$

The equilibrium constant K_c for the reaction A(g) + B(g) C(g) is 0.76 at 150 $\degree$ C. If 0.800 mol of A is added to 0.600 mol of B in a 1.00-L container at 150 $\degree$ C, what will be the equilibrium concentration of C?

A) 0.19 M
B) 0.29 M
C) 0.36 M
D) 0.41 M
E) 0.51 M
