Consider the following reaction:

2H2S(g)+SO2(g)3S(s)+2H2O(g) A reaction mixture initially containing 0.490 M H2S and 0.490 M SO2 was found to contain 1.110³ M H2O at a certain temperature. A second reaction mixture at the same temperature initially contains [H2S]=[H2S]= 0.260 M and [SO2]=[SO2]= 0.315 MM .

Calculate the equilibrium concentration of H2OH2O in the second mixture at this temperature.
