Question

In the contact process, sulfuric acid is manufactured by first oxidizing SO2 to SO3, which is then reacted with water. The reaction of SO2 with O2 is
2SO2(g) 1 O2(g) m 2SO3(g)
A 2.000-L flask was filled with 0.0400 mol SO2 and 0.0200 mol O2. At equilibrium at 900 K, the flask contained 0.0296 mol SO3. How many moles of each substance were in the flask at equilibrium?
