Question

Density is a physical property of a molecule that's measured as mass per unit volume Given that deasity is

usually expressed in the units of g/cm, calculate the density of a cube of plastic that has a mass of 2.331 g and
an edge length of 1.500 cm (volume of a cube is V=b). Be sure to show all steps in the process and include
units throughout the problem.

Answer 1

0.691 g/cm³

Step-by-step explanation:

Mass of cube = 2.331 g

Edge length of cube = 1.500 cm

Volume of cube =
`l^3`

Volume =
`(1.500)^3` cm³

Volume = 1.500×1.500×1.500= 3.375 cm³

`Density=(mass)/(volume) =(2.331)/(3.375) =` 0.691
`(g)/(cm^3)`
