How do you calculate the moles of substances?

Question

I'm doing a lab report about titration of acid (HCl) and base (NaOH). My teacher gave me a bunch of equations, but I don't know how to use them to calculate the moles. If I can't calculate the moles, I won't be able to calculate the molarities of the acid and base.
So far, I have 0.013 L as the volume of HCl. Is there any way to calculate the moles of HCl from only the volume?

Answer 1

You need to know the concentration of HCl. The only thing you know is there are equal moles H+ and CL- ions.
