Under certain conditions the rate of this reaction is zero order in dinitrogen monoxide with a rate constant of 0.0075 Ms^-1: 2N₂O (g)→ 2N₂ (g) + O₂ (8) Suppose a 4.0 L flask is charged under these conditions with 500. mmol of dinitrogen monoxide. How much is left 4.0 s later? You may assume no other reaction is important. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
