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)`

A

80 g

B

64 g

C

120 g

D

160 g

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(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`
