The reaction is:  3 \mathrm{H}_2 \mathrm{~S}+\mathrm{KMnO}_4+\mathrm{H}_2 \mathrm{SO}_4 \rightarrow \mathrm{K}_2 \mathrm{SO}_4+\mathrm{MnSO}_4+4 \mathrm{~S}

So, 3 moles of \mathrm{H}_2 \mathrm{~S} reacts to give 4 moles of Sulphur.

1 mole of \mathrm{H}_2 \mathrm{~S} can give 4/3 moles of sulphur.

2 moles of \mathrm{H}_2 \mathrm{~S} can give 4/3 X 2 = 8/3 moles of sulphur.
