WAEC 2024 CHEMISTRY PRACTICAL ANSWER
VITAL INFORMATION
For question 1
Use your school's endpoint and use it wherever you see our endpoint (18.13cm³) ...and calculate with it

If your school wants to use mine, then the chemistry teacher must submit endpoint similar to ours without much difference...eg 18.13, 18.10, 17.90, 18.20,
