Answer:
13%
Explanation:
Here, as per the given equation, 1 mole of Cl
2
is formed from 1 mole of MnO
2
Therefore,
Number of moles of Cl
2
is n=
22.4L
2.24L
=0.1 mol
Therefore, Mass of Cl
2
is given by W=87g/mol×0.1 mol=8.7 g
Impurity in MnO
2
=10g−8.7g=1.3g
Percentage impurity=
10g
1.3g
×100=13%
Hence, the correct option is D
