The first step to solve this problem is to use the molecular weight of NaOH to convert the given mass to moles (MW=39.997 g/mol):
[tex]33.2g\cdot\frac{mol}{39.997g}=0.83mol[/tex]
Now, divide this amount by the volume of the solution (in liters):
[tex]M=\frac{0.83mol}{0.75L}=1.11M[/tex]
It means that the correct answer is D. 1.11M.
