Q1.

The table shows the student’s results.

The equation for the reaction is: 

C6H8O7 + 3 NaOH ⟶ C6H5O7Na3 + 3 H2O 

The concentration of the sodium hydroxide was 0.102 mol / dm3 

Concordant results are those within 0.10 cm3 of each other. 

Calculate the concentration of the citric acid in mol / dm3 

Use only the concordant results from the table in your calculation.
