SO this is my first time doing this... lol i need help on an AP chemistry question for equilibrium.

A 0.500 L tank contains 3.00 g of NO(g) at 750. K. The equilibrium constant for the reaction
below at this temperature is 3.4 x 10
-3
2NO(g) ⇌ N2(g) + O2(g)

(a) write the equilibrium constant expression for this reaction:

(b) calculate Kc for the reaction 2N2(g) + 2O2(g) ⇌ 4NO(g)

(c) determine the equilibrium concentrations of all species
