N₂O(g) + NO 2 (g)↔️ 3 NO (g)

A 0.0150 mole sample of NO was placed in a 1.00 L flask and allowed to react 145.00 °C producing N20 and NO2.
After the system reacted equilibrium there was 0.00550 moles of NO remaining in the reaction flask.

a.) What are the equilibrium concentrations of all components (reactants and products)?

b.) What is the value K, for this equilibrium?

BONUS What is the value of K p at 145.00 °C for this system?
