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
