In following chemical reaction by taking 159 g of Cu_(2)S,how much gra

1.	In following chemical reaction by taking 159 g of Cu_(2)S,how much gram of SO_(3) produced ? (At. mass of Cu = 63.5, S = 32, O = 16 g/mole) (i) Cu_(2)S + O_(2) rarr Cu_(2)O + SO_(2) (ii) 2SO_(2)+O_(2) rarr 2SO_(3)
Answer» 80 g 64 g 120 g 160 g Solution :`{:(2Cu_(2)S+2O_(2)rarr2Cu_(2)O +2SO_(2)),(2SO_(2) +O_(2) " "rarr2SO_(3)),(BAR(2Cu_(2)S+3O_(2) rarr 2Cu_(2)O+2SO_(3))):}` `{:("ATOMIC mass"159xx2,80xx2),(""159,(?)):}` `rArr (159xx80xx2)/(159xx2)=80G`
