The balanced equation is
<span>8SO2 + 16H2S ----> 3S8 + 16H2O
</span>so
77g SO2 / 64g/mole = 1.203moles  of SO2 
<span>77g H2S / 34g/mole = 2.26moles  of H2S 
</span>now 

<span>1.203 moles SO2 yields 3/8x amount that is = 0.456moles  of S8 
</span>so
<span>2.06moles H2S yields 3/16x amount = 0.386moles of S8 
</span>hence
H2S = produce  only 0.386moles  of S8 = 98.98g S8
