Question

frank has an eraser. it has a mass of 4 g, and a volume of 2 cm³. what is its density? 2 g/cm³ 1/2 g/cm³ 8 g/cm³ 24 g/cm³

Explanation:

Step1: Recall density formula

The formula for density $
ho$ is $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 4$ g and $V=2$ cm³, we substitute into the formula: $
ho=\frac{4}{2}$ g/cm³.

Step3: Calculate density

$\frac{4}{2}=2$ g/cm³.

Answer:

A. $2$ g/cm³
