Answer

Explanation:

Step1: Recall density formula

The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass, and $V$ is volume. We need to solve for $V$, so we can re - arrange the formula to $V = \frac{m}{\rho}$.

Step2: Substitute given values

Given that $m = 25\ g$ and $\rho=5.0\ g/cm^{3}$, we substitute these values into the formula: $V=\frac{25\ g}{5.0\ g/cm^{3}} = 5\ cm^{3}$.

For the second part, elements in the same group of the periodic table have the same number of valence electrons, which leads to similar chemical and physical properties.

Answer:

  1. A. $5\ cm^{3}$
  2. A. True
