Thanks in advance At a certain temperature, this reaction establishes an equilibrium with the given equilibrium constant, Kc. Kc = 1.

I need help with question please. Thanks in advance

At a certain temperature, this reaction establishes an equilibrium with the given equilibrium constant, Kc.

Kc = 1.53 * 10^21

3A (g) + 2B (g) ------> 4C(g)

If, at this temperature, 1.50 mol of A and 4.00 mol of B are placed in a 1.00-L container, what are the concentrations of A, B, and C at equilibrium?
