Final answer:
The units g/ml and g/cm³ represent density, s represents time, km, cm³, and mm represent length, g and mg symbolize mass, and L signifies volume. These units are assigned according to the metric system or SI units for easy and consistent scientific measurements.
Step-by-step explanation:
The units given, namely g/ml, s, km, g, cm³, mm, mg, L, and g/cm³, each represent certain types of measurements. Specifically, g/ml and g/cm³ are both units for the measurement of density, defining mass per unit volume. The second (s) unit measures time. Kilometers (km), centimeters (cm³), and millimeters (mm) are all units used for length measurement. The gram (g) and milligram (mg) units both represent mass. Finally, the litre (L) is a unit denoting volume. These are all standard metric or SI units used in scientific measurements, making comparisons and calculations conveniently possible through factors of 10.
