Step-by-step explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,
Molarity
n= moles of solute
= volume of solution in ml

According to stoichiometry:
1 mole of
gives 2 moles of

1.653 mmol of
gives =
of

Thus number of millimoles of
are 3.306
