Question

the density of nickel is 8.9g/cm3. the sample weighs 500g. what is the volume of of this sample
0.018cm3
56.1cm3
4450cm3

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 $V$, so we can re - arrange the formula to $V = \frac{m}{
ho}$.

Step2: Substitute values

Given that $m = 500g$ and $
ho=8.9g/cm^{3}$, we substitute these values into the formula: $V=\frac{500g}{8.9g/cm^{3}}$.

Step3: Calculate volume

$V=\frac{500}{8.9}\ cm^{3}\approx56.1\ cm^{3}$.

Answer:

56.1cm3
