Analyte HCl
Mole of Analyte (HCl)
(Equal to the moles of titrant)

Concentration (M)of analyte (HCl)
Step 1- divide volume dispensed of analyte by 1000 to get L of analyte
Step 2- Divide moles of analyte by liters of analyte to get concentration.

Average concentration(M) of analyte.
Add up the analyte concentrations from the three trials. Divide your answer by 3. Include 3 significant digits in your answer.

Percent error of concentration (M) of analyte.

Actual concentration of HCl = 0.120 M
Experimental concentration- Use the average you calculated.

Step 1- Subtract experimental value from actual value.
Step 2- Divide answer in Step 1 by actual value.
Step 3- Multiply answer in Step 3 by 100.

Your answer should be expressed as a percentage.
