Answer: Molarity of anions in the chemist's solution is 0.0104 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute
= volume of solution in ml = 100 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be
As 1 mole of gives 2 moles of
Thus moles of
gives =
Thus the molarity of anions in the chemist's solution is 0.0104 M
