Question

A vinegar (acetic acid) solution of unknown concentration was titrated to the light pink endpoint with the standardized NaOH solution.


A vinegar (acetic acid) solution of unknown concentration was titrated to the light pink endpoint with the standardized NaOH solution. The weight volume % of the vinegar solution were calculated. 

Molecular formula of Acetic acid: C2H4O2 

Volume of vinegar sample titrated (ml) 5.00 

Volume of NaOH required to neutralize vinegar in (mL) 8.74 

Concentration of NaOH in mol/L, 0.1979 

Calculate the weight/volume percentage of the vinegar solution (g/100 ml).
