Eq. mass=(molecular mass/n - factor) As2+3 → 2A s+5 n-factor 4 S2-2 → 3 overset+6S 24 total n-factor = 28 Eq. mass =(m.wt/28)

Q. $28 N O_{3}^{-} + 3 A s_{2} S_{3} + 4 H_{2} O \to 6 A S O_{4}^{3 -} + 28 NO + 9 S O_{3}^{2 -} + H^{+}$ What will be the equivalent mass of $A s_{2} S_{3}$ in the above reaction?

$\frac{M . wt}{2}$

$\frac{M . wt}{4}$

$\frac{M . wt}{24}$

$\frac{M . wt}{28}$

$Eq . ma ss = \frac{m o l ec u l a r ma ss}{n - f a c t or}$
$A s_{2}^{+ 3} \to 2 A s^{+ 5} n - f a c t or 4$
$S_{2}^{- 2} \to 3 S + 6 24$
total n-factor $= 28$
$Eq . ma ss = \frac{m . wt}{28}$
