Answer: 3.306 mmol
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
5 mols = 100 grams
1 mol = 100/5
1 mol = 20 grams.
