A mixture `x` containing 0.02 mol of `[Co(NH_(3))_(5) SO_(4)]Br` and 0.02 mol of `[Co(NH_(3))_(5)Br]SO_(4)` was prepared in `2 L` of solution.
`1 L` of mixture `X + ` excess `AgNO_(3) rarr Y`
`1 L` of mixture `X +` excess `BaCl_(2) rarr Z`
The number of moles of `Y` and `Z` are

Options

A. (a) `0.01, 0.01`
B. (b) `0.02, 0.01`
C. (c) `0.01, 0.02`
D. (d) `0.02, 0.02`

Answer

A

Explanation

`underset(0.02 "mole")[[Co(NH_3)_5SO_4]]Br+AgNO_3rarrunderset(0.02 "mole"(Y))[[Co(NH_3)_5.SO_4]]NO_3+AgBr`
`underset(0.02 "mole")[[Co(NH_3)_5Br_2]]SO_4+BaCl_2rarrunderset(0.02 "mole" (Z))[[Co(NH_3)_5Br]]Cl_2+BaSO_4`
On using 1 L solution, we will get `0.01` mole Y and `0.01` mole Z.
