Question

1. a rock has a density of 4 g/ml and a mass of 16 g. find the volume of the rock.

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. We need to find $V$, so we can re - arrange the formula to $V = \frac{m}{
ho}$.

Step2: Substitute given values

We are given that $m = 16\ g$ and $
ho=4\ g/mL$. Substituting these values into the formula $V=\frac{m}{
ho}$, we get $V=\frac{16\ g}{4\ g/mL}$.

Step3: Calculate volume

$V = 4\ mL$.

Answer:

$4\ mL$
