Ranks the objects from most to least dense : X,Z,Y,W

Given

Object W : m=16 g, V=84 cm³

Object X : m=12 g, V= 5 cm³

Object Y : m=4 g, V= 6 cm³

Object Z : m=408 g g, V= 216 cm³

Required

Density

Solution

Density formula:

[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]

ρ = density

m = mass

v = volume

1. Object W

[tex]\tt \rho=\dfrac{16}{84}=0.19[/tex]

2. Object X

[tex]\tt \rho=\dfrac{12}{5}=2.4[/tex]

3. Object Y

[tex]\tt \rho=\dfrac{4}{6}=0.67[/tex]

4. Object Z

[tex]\tt \rho=\dfrac{408}{216}=1.89[/tex]

From most to least dense : X,Z,Y,W
