76 gram of a silver salt of dibasic acid on heating left a residue of 54 gram silver. Silver salt contains only and in mole ratio of then find the mass of gas liberated during ignition of 76 gm silver salt ( )
Options:
Answer:
D
Solution:
Ag residue = 54 g
Moles of Ag =
Dibasic acid silver salt ⇒ 2 Ag per molecule
Moles of salt =
C : O = 1 : 2 ⇒ CO₂ group
CO₂ released = 0.25 × 44 = 11 g
But only 1/50 part of CO₂ is liberated according to composition relation ⇒
