C10H6S is the compound given
Atomic weights : C=12, H=1, S= 32
Molar mass : 12*10+6*1+32=158 g/mole
C10H6S is formed from ------->10C+6H +1S =10 mole of C + 6 moles of H+ 1 mole of Sulfur
120 gm of C +6 gm of hydrogen +32 gm of sulfur
158 gm of allyl sulfide will have 1 mole of Sulfur
22.7 gm of allyl sulfide will have 22.7/158=0.14 moles
158 gm of allyl sulfide will have 120 gm of sulfur
44.8 gm of allyl sulfie will have 44.8*120/158= 34.02 gm
