If you needed to use powdered magnesium oxide in an experiment and were only supplied with clumps of magnesium oxide which tool would you need to convert the magnesium oxide to usable form?

To convert clumps of magnesium oxide into a usable powdered form, you would need a mortar and pestle. This tool allows you to grind the clumps into a fine powder, ensuring that the magnesium oxide can be used effectively in your experiment. Alternatively, a mechanical grinder or blender could also be used for larger quantities.
