At a certain temperature, a 22.0-L container holds four gases in equilibrium. Their masses are 3.5 gSO 3
,4.6 gSO 2
,15.6 g N 2
, and 0.98 g N 2
O What is the value of the equilibrium constant at this temperature for the reaction of SO 2
with N 2
O to form SO 3
and N 2
? Make sure you balance the reaction using the lowest whole-number coefficients. K c
