Question

jeans has an object made of pure zinc with a mass of 12 grams. what is the objects volume if zinc has a density of 4 g/cm³?

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 solve for $V$.

Step2: Rearrange the formula for volume

Rearranging $
ho=\frac{m}{V}$ gives $V = \frac{m}{
ho}$.

Step3: Substitute values

We know $m = 12$ g and $
ho=4$ g/cm³. Substituting these values into the formula $V=\frac{m}{
ho}$, we get $V=\frac{12}{4}$.

Step4: Calculate the volume

$V = 3$ cm³.

Answer:

3 cm³
