Question

1. a 10.0 cm³ sample of copper has a mass of 89.6 g. what is the density of copper? answer: ______

Explanation:

Step1: Recall density formula

Density ($
ho$) is defined as mass ($m$) divided by volume ($V$), so the formula is $
ho = \frac{m}{V}$.

Step2: Identify given values

Mass $m = 89.6\,\text{g}$ and volume $V = 10.0\,\text{cm}^3$.

Step3: Substitute values into formula

Substitute $m = 89.6\,\text{g}$ and $V = 10.0\,\text{cm}^3$ into $
ho = \frac{m}{V}$, we get $
ho = \frac{89.6\,\text{g}}{10.0\,\text{cm}^3}$.

Step4: Calculate the density

$\frac{89.6}{10.0} = 8.96\,\text{g/cm}^3$.

Answer:

The density of copper is $8.96\,\text{g/cm}^3$.
