22. What is the appropriate unit of measure to express the weight of a spoon?

Answer: A

Explanation:

Gram is the appropriate unit of measure to express the weight of a spoon.

The weight of a spoon is most accurately expressed in grams, as it is a small object where finer measurements are necessary for precision.

A) Gram

This option is correct because grams are the standard unit of measurement for weight in the metric system, particularly for small items like a spoon. Measuring the weight of a spoon in grams allows for accurate and precise quantification.

B) Liter

This option is incorrect as liters measure volume, not weight. A spoon's weight cannot be expressed in liters because it does not represent the amount of space the spoon occupies.

C) Kilogram

While kilograms are a unit of weight, they are typically used for heavier objects. Measuring a spoon in kilograms would not provide a practical or precise weight representation since spoons generally weigh only a few grams.

D) Milliliter

This option is incorrect because milliliters measure volume rather than weight. A spoon's weight cannot be accurately expressed in milliliters as it does not pertain to the physical weight of the object.

Conclusion

In conclusion, the gram is the most appropriate unit to express the weight of a spoon due to its suitability for small measurements. All other options either measure volume or are too large to accurately represent the weight of a spoon, confirming that option A is the definitive choice.
