Question

Reaction of $xg$ of $Sn$ with $HCl$ quantitatively produced a salt. Entire amount of the salt reacted with $yg$ of
nitrobenzene in the presence of required amount of $HCl$ to produce $1.29g$ of an organic salt (quantitatively).
(Use Molar masses (in $gmo{l}^{–1}$) of $H,C,N,O,Cl$ and $Sn$ as

The value of $x$ is .

Answer 1

$Sn+2HCl\to SnC{l}_2+H_2$
Moles of $Sn=\frac{x}{119}$
Moles of nitrobenzene $=\frac{x}{119}\times \frac{1}{3}$
Moles of anilium chloride $=\frac{x}{119}\times \frac{1}{3}$
Moles of nitrobenzene $=\frac{x}{357}$
$\frac{y}{123}=\frac{x}{357}$ ...(1)
Moles of anilium chloride $=\frac{x}{357}$ ...(2)
$\frac{1.29}{129}=\frac{x}{357}$
$x=3.57$
