What is the concentration of hydrochloric acid if 0.1m/dm^3 of sodium hydroxide is used, and 32ml^3 is used of it to make the titration occur?

We want the quotient...#"molarity"="moles of solute"/"volume of solution"#

Explanation:

And we interrogate the reaction...

#HCl(aq) + NaOH(aq) rarr NaCl(aq) + H_2O(l)#..

Now we can work out the moles of sodium hydroxide...i.e.

#0.1*mol*dm^-3xx32xx10^-3*dm^3=3.20*mmol#.

Now there is equimolar #HCl#, BUT, we DO NOT KNOW the volume in which the hydrogen chloride coreactant was dissolved...and so there are insufficient data...
