Which tool is most appropriate for measuring the mass of a serving cheese?

The most appropriate tool for measuring the mass of a serving of cheese is a kitchen scale.

Here's why:

* Accuracy: Kitchen scales are designed to provide accurate measurements in grams or ounces, which are standard units for measuring mass.

* Convenience: They are readily available and relatively inexpensive.

* Versatility: Kitchen scales can be used for measuring a variety of ingredients, not just cheese.

While other options like measuring cups or spoons might be used for volume, they are not as precise for determining mass, which is the amount of matter in an object.
