• A. True
• B. False

Answer 1

The correct option is A True

1. Density can be defined as mass per unit volume.
2. The SI unit of density is $kg/m³$while the CGS unit is $g/cm³$
3. Density is a measure of how much mass is contained in a given amount of space (volume)
4. Mercury has the highest density at standard temperature and pressure.
5. Density of mercury, iron, copper, and aluminum are given below

Iron	7850
Copper	8940
Aluminum	2712
Mercury	13593

Hence, Among mercury, iron, copper, and aluminum, mercury has the highest density.
