The density of an object is equal to the mass of the object divided by the volume of the object, which can be expressed as density=
mass
volume
. Thus, if an object has a density of 3 grams per milliliter and a mass of 24 grams, the equation becomes 3grams/milliliter=
24grams
volume
This can be rewritten as volume =
24grams
3
grams/milliliter=8 milliliters Choice A is incorrect and be may be the result of confusing the density and the volume and setting up the density equation as 24=
3
volume
. Choice C is incorrect and may be the result of a conceptual error that leads to subtracting 3 from 24. Choice D is incorrect and may be the result of confusing the mass and the volume and setting up the density equation as 24=
