Question

jack has a rock. the rock has a mass of 14 g and a volume of 2 cm³. what is the density of the rock? 7 g/cm³ 28 g/cm³ 7 ml 1/7 g/cm³

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 14$ g and $V=2$ cm³, then $
ho=\frac{14}{2}$ g/cm³.

Step3: Calculate density

$\frac{14}{2}=7$ g/cm³.

Answer:

7 g/cm³
