Accepted Answer

Given, weight of organic compound = 0.25 g

Moles of AgCl = $\frac{0.4}{M}$

Molecular mass of AgCl (M) = 143.5 gm

$∴$ Moles of AgCl = $\frac{0.4}{143.5}$

$∴$ Mass of Cl = $\frac{0.4}{143.5}$ $\times$ 35.5

Mass % of Cl in the organic compound

$= \frac{\frac{35.5 \times 0.4}{143.5}}{0.25} \times 35.5$

$= 39.58$

$≃ 40$
