Vaibhav,
Please tell me how did you get the answer.
Mixture X=0.02 moles of [Co(NH3)5SO4]Br and 0.02 moles of [Co(NH3)5Br]SO4 was prepared in 2 L of solution:
1 L of mixture X+excess of AgNO3→Y
1 L of mixture X+excess of BaCl2→Z
Number of moles of Y and Z are:
a)0.01,0.01
b)0.02,0.01
c)0.01,0.02
d)0.02,0.02.
for Y:
[Co(NH3)5SO4]Br → Br-
moles→ 0.01 0.01
AgNO3 + Br- → AgBr (Y)
moles→ excess 0.01 0.01
similarly do it for Z
