the density of an object is defined as:
a. the volume occupied by each unit of mass.
b. the amount of mass for each unit of volume.
c. the weight of each unit of volume.
d. the amount of the substance that has unit volume and unit mass.
e. the amount of the substance that contains as many particles as 12 grams of the carbon - 12 isotope.
o a
o d
o c
o b

Explanation:

Density is a fundamental concept in physics and chemistry, defined as mass per unit volume. It measures how much mass is contained within a given volume of a substance. Options a, c, d, and e do not correctly define density. Option a is the reciprocal of density. Option c refers to weight instead of mass. Option d is an incorrect description. Option e defines the mole concept, not density.

Answer:

B. the amount of mass for each unit of volume.
