Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,
n= moles of solute
= volume of solution in ml
Given : moles of
= 6.89
volume of solution = 200 ml
Putting in the values we get:

Thus the concentration of the chemist's sodium chloride solution is 34.4 mol/L.
