Answer : The molarity of a solution is 0.554 M.
Explanation : Given,
Mass of
= 16.8 g
Volume of solution = 300.0 mL
Molar mass of
= 101.11 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Therefore, the molarity of a solution is 0.554 M.
