SO2(g) + 2H2S(g) --> 2H2O(l) + 3S(s)
100 cm^3 SO2 remains

volumes are proportional to moles of gas
2 volumes of H2S react with 1 volume of SO2 (ratio 2:1)
300 cm^2 H2S reacts with 150 cm^3 SO2
250 cm^3 - 150 cm^3 = 100 cm^3 SO2
 
250cm^3 of so2 and 300cm^3 of h2s reacted together according to the following equation:

so2 + 2H2S = 2H2O + 3S

what volume of gas will be left at the end of the reaction?

ALL AT STP
