22. a bar of silver has a mass of 68.0 g and a volume of 6.48 cm³. what is the density of silver?

Explanation:

Step1: Recall density formula

Density ($\rho$) is given by $\rho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 68.0\ g$ and $V=6.48\ cm^{3}$, then $\rho=\frac{68.0\ g}{6.48\ cm^{3}}$.

Step3: Calculate density

$\rho\approx 10.5\ g/cm^{3}$

Answer:

$10.5\ g/cm^{3}$
