Answer 1

The student should stop the experiment and inform the teacher.

Step-by-step explanation:

When a student loses track during a solvent extraction experiment, the best course of action is to stop the experiment and inform the teacher. Continuing without tracking the progress can lead to inaccurate results and potentially hazardous situations. Starting the experiment again from the beginning may be necessary if important information was missed, and asking a classmate for help can provide additional guidance and support.
