$6$ mol of a mixture containing same number of moles of $N a N O_{3}, N H_{4} N O_{3}, L i N O_{3}, C a (N O_{3})_{2}, P b (N O_{3})_{2}$ and $A g N O_{3}$ , was heated strongly. Total number of moles of $O_{2} (g)$ evolved is :

Solution

6 compounds have 1 mole each.
$N H_{4} N O_{3}$ does not give $O_{2}$ .
$2 L i N O_{3} 1 m o l e \to L i_{2} O + 2 N O_{2} + \frac{1}{2} O_{2} (0.25 m o l e)$
$2 C a (N O_{3})_{2} (1 m o l e) \to 2 C a O + 4 N O_{2} + O_{2} (0.5 m o l e)$
$2 P b (N O_{3})_{2} (1 m o l e) \to 2 P b O + 4 N O_{2} + O_{2} (0.5 m o l e)$
$2 A g (N O_{3})_{2} (1 m o l e) \to 2 A g + 2 N O_{2} + O_{2} (0.5 m o l e)$
$2 N a (N O_{3})_{2} (1 m o l e) \to N a_{2} O + O_{2} (0.5 m o l e) + N O + N O_{2}$
Total number of moles of $O_{2}$ evolved $= 2.25$
