What volume of $${3}$$ molar $${H}{N}{O}_{{{3}}}$$ is needed to oxidise $${8}{g}$$ of $${F}{e}^{{{3}+}}$$, $${H}{N}{O}_{{{3}}}$$ gets converted to $${N}{O}$$ ?
(A) $${8}{m}{L}$$
(B) $${16}{m}{L}$$
(C) $${32}{m}{L}$$
(D) $${64}{m}{L}$$

Meq.of $${H}{N}{O}_{{{3}}}=\text{Meq.of}{F}{e}^{{{3}+}}$$
$${\left[\text{Eq.of}{H}{N}{O}_{{{3}}}={M}/{3}\right]}$$
or $${3}\times{3}\times{V}=\frac{{{8}}}{{{56}}}\times{1000}$$
$$\therefore{V}={15.87}{m}{L}$$
