\( 5 \mathrm{~g} \) sample of brass was dissolved in one litre conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \cdot 20 \mathrm{~mL} \) of this solution were mixed with \( \mathrm{KI} \),
\( \mathrm{P} \)
liberating \( \mathrm{I}_{2} \) and \( \mathrm{Cu}^{+} \)and the \( \mathrm{I}_{2} \) required \( 20 \mathrm{~mL} \) of
W
\( 0.0327 \mathrm{~N} \) hypo solution for complete titration. Calculate the percentage of \( \mathrm{Cu} \) in the alloy.
