Question

How many moles of chlorine, cl, are there in 8 moles of carbon tetrachloride, ccl4?

Answer 1

Moles are the amount of substance

the break down of CCl₄ is as follows

CCl₄ --> C + 4 Cl

in the compound CCl₄ - 1 mol of CCl₄ contains 4 mol of Cl

so for every 1 mol of CCl₄ there are 4 mol of Cl

then in 8 mol of CCl₄ - there are 4 x 8 = 32 mol of Cl

so 8 mol of CCl₄ contains 32 mol of Cl

answer is 32 mol of Cl

Answer 2

$\boxed{{\text{32 moles}}}$ of chlorine are present in 8 moles of ${\text{CC}}{{\text{1}}_{\text{4}}}$ .

Further Explanation:

Mole is a measure of the amount of substance. It is defined as the mass of a substance that has the same number of fundamental units as there are atoms in 12 g of carbon-12. Such fundamental units can be atoms, molecules or formula units.

In ${\text{CC}}{{\text{l}}_4}$ , both carbon and chlorine are non-metals. Carbon has four valence electrons whereas chlorine has seven valence electrons. Both share two electrons with each other and a single covalent bond is formed between a carbon and a chlorine atom. So carbon forms four single bonds with four chlorine atoms in order to complete its octet and the octet of chlorine is also fulfilled. This bond is formed due to sharing of the electrons and therefore ${\text{CC}}{{\text{l}}_4}$ is a covalent compound. (Refer to the attached image)

${\text{CC}}{{\text{l}}_4}$ is a covalent compound. So 1 mole of  ${\text{CC}}{{\text{1}}_{\text{4}}}$ contains 1 mole of carbon and 4 moles of Cl.

Number of moles of Cl in 1 mole of ${\text{CC}}{{\text{l}}_4}$ = 4

So the number of moles of Cl in 8 moles of ${\text{CC}}{{\text{l}}_4}$ is calculated as follows:

$\begin{aligned}{\text{Moles of Cl}}&=\left({8\;{\text{mol}}\;{\text{CC}}{{\text{l}}_4}}\right)\times \left({\frac{{4\;{\text{mol}}\;{\text{Cl}}}}{{1\;{\text{mol}}\;{\text{CC}}{{\text{l}}_4}}}}\right)\\ &=\boxed{32\;{\text{mol}}}\\\end{gathered}$

So 8 moles of ${\mathbf{CC}}{{\mathbf{l}}_{\mathbf{4}}}$  contain 32 moles of Cl.
