The mole connects the microscopic world of atoms and molecules to measurable laboratory amounts. One mole contains exactly the Avogadro constant number of specified entities.
It is chemistry’s counting unit: like a dozen, but designed for unimaginably small objects.

Choose a concrete case linked to The mole and Avogadro constant. Write down the known information, what you are trying to find, and the units. Then state the rule, model or trend you will use. If a calculation is involved, keep the units visible at every line; if it is conceptual, state what changes and what remains fixed.
A strong answer contains four things: the starting situation, the variable that changes, the direction or numerical result, and one check. The check can be a unit, an order of magnitude, a limiting case or a comparison with a familiar example.
