Homework Help: Titration Calculation of Unknown Solution

  1. May 28, 2012 #1
    1. The problem statement, all variables and given/known data
    I titrated an unknown sample with a Sodium Hydroxide 250cm3 with 0.1M Concentration. I titrate and used up 17 cm3 using a Hydrochloric Acid to neutralise the NaOH. I have to find out the Mole of the unknown substance

    2. Relevant equations

    I forgot the equations of titration, all I can find on the internet I cant understand them.. >.<

    3. The attempt at a solution

    I used the 0.1 mol dm-3 NaOH and got 19.3cm3 HCl , that would be equal to 0.83 M,

    i find the easiest way of remembering the equation is to think of a triangle:
    concentration * volume

    so mol = concentration * volume
    concentration = mol/volume
    volume = mol/concentration
