Answer: 0.22 M
Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

moles of 

Thus moles of
= 0.011
According to stoichiometry:
2 moles of
require 1 mole of 
Thus 0.011 moles of
require=
moles of 
Thus Molarity of 
Therefore, the molarity of
in the solution is 0.22 M
