The treatment of an aqueous solution of

3.74 \mathrm{~g}

of

\mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}

with excess KI results in a brown solution along with the formation of a precipitate. Passing

\mathrm{H}_{2} \mathrm{~S}

through this brown solution gives another precipitate

\mathbf{X}

. The amount of

\mathbf{X}

(in

g

) is

\underline{\hspace{2cm}}

. [Given: Atomic mass of

\mathrm{H}=1, \mathrm{~N}=14, \mathrm{O}=16, \mathrm{~S}=32, \mathrm{~K}=39, \mathrm{Cu}=63, \mathrm{I}=127
