MARKS App · Accepted Answer

Here, the mass of the substance taken $=0.3780 \mathrm{~g}$ Mass of $\mathrm{AgCl}$ formed $=0.5740 \mathrm{~g}$ Now 1 mole of $\mathrm{AgCl} \equiv 1 \mathrm{~g}$ atom of $\mathrm{Cl}$ or $(108+35.5)=143.5 \mathrm{~g}$ of $\mathrm{AgCl} \equiv 35.5 \mathrm{~g}$ of $\mathrm{Cl}$ Applying the relation, Percentage of chlorine $=\frac{35.5}{143.5} \times \frac{\text { Mass of } \mathrm{AgCl} \text { formed }}{\text { Mass of substance taken }} \times 100$ $=\frac{35.5}{143.5} \times \frac{0.5740}{0.3780} \times 100=37.56 \%$
