Question

At a certain temperature, a 19.0-L contains holds four gases in equilibrium. Their masses are: 3.5 g SO3, 4.6 g SO2, 14.0 g N2, and 0.98 g N2O. What is the value of the equilibrium constant at this temperature for the reaction of SO2 with N2O to form SO3 and N2 (balanced with lowest whole-number coefficients)?

Answer 1

This really is just a substitute the numbers and solve. Tell me what your problem is. If we can clear up some confusion I'll bet you can do this on your own.
