A mass measurement is typically expressed in which units for common lab scales?

Explanation:
On most lab scales the reading represents mass—the amount of matter in an object. Mass is typically expressed in grams or kilograms because these units suit the small to moderately large amounts scientists work with. Liters measure volume, not how much matter is present, so they wouldn’t be used for mass. Newtons measure force (weight is mass times gravity), and seconds measure time, neither of which is what a standard mass scale displays. Remember that mass and weight are related but different: mass is an intrinsic property, while weight depends on gravity. That’s why you’ll usually see readings in grams or kilograms, with 1 kilogram equal to 1000 grams.
