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

Answer:

0.691 g/cm³

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

$Density=\frac{mass}{volume} =\frac{2.331}{3.375} =$ 0.691 $\frac{g}{cm^3}$
