21.75g of

Mn{O_2}

on reaction with HCl forms 2.8 L of

C{l_2}\left( g \right)

at STP, the percentage purity of

Mn{O_2}

is (atomic mass of Mn = 55u)

Mn{O_2} + 4HCl \to MnC{l_2} + C{l_2} + 2{H_2}O

View answer and explanation

Correct option: D

0.5

Option D (0.5) is correct because the percentage purity is calculated by comparing the actual volume of Cl2 produced to the theoretical volume based on the amount of MnO2 used.
