Question

2. 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: 0.6906 g/cm^3

Step-by-step explanation:

`$$We know that density $=\frac{\text { mass }}{\text { volume }}$\\\\Volume of the cube, $V=l^(3)=(1.500 \mathrm{~cm})=3.375 \mathrm{~cm}^(3)$\\\\Density of the cube $=\frac{2.331 \mathrm{~g}}{3.375 \mathrm{~cm}^(3)}=0.6906 \mathrm{~g} / \mathrm{cm}^(3)$\\\\ \therefore{\text{Density of the cube,} \ $\rho_{\text {cube }}{=0.6906 \mathrm{~g} / \mathrm{cm}^(3)$`
