Question

7. What is density?????​

Answer 1

Answer:

The density of a liquid is a measure of how much mass is contained within a given unit volume (density = mass divided by volume). If mass is a measure of how much “stuff” there is in an object or liquid, density is a measure of how tightly that “stuff” is packed together. ... Densities may vary from brand to brand.

Answer 2

• The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume.
• The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.
• Mathematically, density is defined as mass divided by volume
