Solution

Solution Steps

Step 1: Determine the Chemical Composition of $\mathrm{CaCl}_2$

Calcium chloride ($\mathrm{CaCl}_2$) is composed of one calcium atom and two chlorine atoms. Therefore, each mole of $\mathrm{CaCl}_2$ contains two moles of chlorine atoms.

Step 2: Calculate the Moles of Chlorine

Given that there are $3.5$ moles of $\mathrm{CaCl}_2$, and knowing that each mole of $\mathrm{CaCl}_2$ contains two moles of chlorine, we can calculate the total moles of chlorine:

\[ \nu_{\mathrm{Cl}} = 3.5 \, \text{mol} \times 2 = 7.0 \, \text{mol} \]
