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?

• Chemistry -

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.
