Answer: There are 5.2 moles of Cl are present in 2.6 mol [tex]CaCl_{2}[/tex].
Explanation:
Given: Moles of [tex]CaCl_{2}[/tex] = 2.6 mol
In a molecule of [tex]CaCl_{2}[/tex] there are 2 atoms of chlorine present. Therefore, moles of chlorine are present as follows.
[tex]2.6 mol CaCl_{2} \times \frac{2 mol Cl_{2}}{1 mol CaCl_{2}}\\5.2 mol Cl_{2}[/tex]
Thus, we can conclude that there are 5.2 moles of Cl are present in 2.6 mol [tex]CaCl_{2}[/tex].
