do now: jeans has an object made of pure zinc with a mass of 12 grams. what is the objects volume if zinc…

Explanation:

Step1: Recall density formula

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

Step2: Substitute given values

We are given that $m = 12$ grams and $\rho=4\ g/cm^{3}$. Substituting these values into the formula $V=\frac{m}{\rho}$, we get $V=\frac{12\ g}{4\ g/cm^{3}}$.

Step3: Calculate volume

$V = 3\ cm^{3}$

Answer:

$3\ cm^{3}$
