By starting with 0.5 moles of sodium peroxide how many moles of dioxygen gas can be obtained by dropping excess of acidified potassium permanganate solution on it?

Options:

Answer:

Solution:

$2 K M n O_{4} + 5 N a_{2} O_{2} + 8 H_{2} S O_{4} \to K_{2} S O_{4} + 2 M n S O_{4} + 5 N a_{2} S O_{4} + 8 H_{2} O + 5 O_{2}$
$5 mole {Na}_{2} O_{2} O_{2} = 5$ gives $O_{2} = 5 mole$
So $0 .5 mol {Na}_{2} O_{2}$ give $O_{2} = 0 .5 mol$
