Which unit is appropriate for measuring mass in the metric system?

• A. Liter
• B. Gram
• C. Meter
• D. Newton

Answer: (B)

Mass is the amount of matter in an object, and in the metric system the gram is the unit used to measure that amount (with the kilogram as the larger base unit). One kilogram equals 1000 grams, so grams are convenient for everyday masses. The liter measures volume (how much space a substance takes up), the meter measures length (distance), and the newton measures force. Since we're talking about how much matter there is, the gram is the appropriate unit.
