frank has an eraser. it has a density of 2.0 g/cm³, and a volume of 2.0cm³. what is its mass?
o 4.0g
o 1.0g
o 2.0g
o 1.5g

Explanation:

Step1: Recall density - mass - volume formula

The formula is $M = D\times V$, where $M$ is mass, $D$ is density, and $V$ is volume.

Step2: Substitute given values

Given $D = 2.0\ g/cm^{3}$ and $V=2.0\ cm^{3}$, then $M=2.0\ g/cm^{3}\times2.0\ cm^{3}$.

Step3: Calculate mass

$M = 4.0\ g$.

Answer:

$4.0\ g$
