Question

a sample of metal has a mass of 15.90 g, and a volume of 4.32 ml. what is the density of this metal? g/cm³

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Convert volume units

Since $1\ mL = 1\ cm^{3}$, the volume $V = 4.32\ cm^{3}$ and $m=15.90\ g$.

Step3: Calculate density

$
ho=\frac{15.90\ g}{4.32\ cm^{3}}\approx3.68\ g/cm^{3}$

Answer:

$3.68$
