At a certain temperature, a 19.0-L container holds four gases in equilibrium. Their masses are 3.5 gSO,4.6 gSO₂ ,22.0 g N. and 0.98 g N₂ O. What is the value of the equilibrium constant at this temperature for the reaction of SO₂with N₂ O to form SO₃ and N₂? Make sure you balance the reaction using the lowest whole-number coefficients.
