Question

If the mass of a material is 122 grams and the volume of the material is 25 cm3, what would the density of the material be?

Your Answer______ Units__

Answer 1

The answer is 4.88, measured as units of grams/cm³.
We calculate the density as the measurement of the amount of mass per unit of volume, by dividing the mass by its volume:
density = mass/volume
= 122 grams / 25 cm³
= 4.88 grams/cm³
This material with a density that is greater than 1 gram/cm³ will sink in water (whose density is approximately 1 gram/cm³) because it is denser.
