2022 WAEC CHEMISTRY PRACTICAL ANSWERS

For question 1

Use your school’s endpoint and use it wherever you see our endpoint (24.10cm³) …and calculate with it

Use the answer you got in 1b(i) to solve in 1b(ii) i.e we got 0.0482, as u can see, we used it in 1bii.

If your school wants to use mine, then the chemistry teacher must submit endpoint similar to ours without much difference…eg 24.10, 24.20, 24.30, etc.
