a. As the mass of an object increases, the density of the object increases.
b. As the mass of an object increases, the density of the object decreases.
c. As the mass of an object decreases, the density of the object increases.
d. As the mass of an object decreases, the density of the object decreases.

Answer 1

Answer 2

density = mass/volume
That is, density is proportional to mass
so, with constant volume, greater(smaller) mass means greater(smaller) density
