Answer: Concentration of the chemist's sodium chloride solution is 34.4 mol/L.

Step-by-step explanation:

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


Molarity=(n* 1000)/(V_s)

where,

n= moles of solute


V_s = volume of solution in ml

Given : moles of
NaCl = 6.89

volume of solution = 200 ml

Putting in the values we get:


Molarity=(6.89* 1000)/(200)=34.4mol/L

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