Q. $H_{2} O_{2}$ is oxidised by $M n O_{4}^{-}$ in acidic medium to form $O_{2}$ and $M n^{2 +}$ . How many gram of $O_{2}$ are produced from $1.5 \times 1 0^{- 3}$ moles of $M n O_{4}$ and $1.2$ milligram of $H_{2} O_{2}$ :-

$1.13 \times 1 0^{- 3}$

$2.5 \times 1 0^{- 3}$

$7.5 \times 1 0^{- 4}$

$0.35 \times 1 0^{- 5}$

$\frac{1.2 \times 1 0 ^{- 3}}{34} \times 32$ wt of $O_{2}$
$1.12 \times 1 0^{- 3} g m$ of $O_{2}$
