Question

Consider the following reaction: 2 H2O(g) + 2 SO2(g) ↔ 2 H2S(g) + 3 O2(g) A reaction mixture initially contains 2.8 M H2O and 2.6 M SO2. Determine the equilibrium concentration of H2S if Kc for the reaction at this temperature is 1.3 × 10-6. Consider the following reaction: 2 H2O(g) + 2 SO2(g) ↔ 2 H2S(g) + 3 O2(g) A reaction mixture initially contains 2.8 M H2O and 2.6 M SO2. Determine the equilibrium concentration of H2S if Kc for the reaction at this temperature is 1.3 × 10-6. 0.058 M 0.12 M 3.1 × 10-3 M 0.028 M 0.045 M

This problem is posted already but they are using an exponent for O2 = to 2 instead of 3. I am tired and this is confusing me. In addition the problem answer does not go into detail. Can you please explain the steps with reasoning? Thank you in advance for your time.
