How do i determine the exact molarity of .2 M of HCL?
The molarity of NaOH Used was .2010M used in the titration. And the volume used 10.33 mL used to reach equivalence point. What would be the Molarity of HCL?

It is unclear to me about the exact volumes and what is titrating what; however, here is how you do the problem.
Write and balance the equation.
HCl + NaOH ==> NaCl + H2O
moles NaOH = MNaOH x LNaOH = ??
Using the coefficients in the balanced equation, convert moles NaOH to moles HCl. It is 1:1; therefore, moles NaOH = moles HCl.
Then M HCl = molesHCl/LHCl.
