Answer :

Final answer:

To find the number of moles of chlorine in 38.5 moles of CCl₂F₂, you multiply 38.5 by 2 (since there are two chlorine atoms per molecule), resulting in 77 moles of Cl.

Explanation:

The question asks us to calculate the number of moles of chlorine (Cl) in a given amount of dichlorodifluoromethane (CCl₂F₂). The molecular formula CCl₂F₂ tells us that there are two chlorine atoms in each molecule of CCl₂F₂. Therefore, for every mole of CCl₂F₂, there are two moles of chlorine atoms.

Since the student has 38.5 moles of CCl₂F₂, we simply need to multiply the number of moles of CCl₂F₂ by the number of chlorine atoms per molecule:

38.5 moles of CCl₂F₂ × 2 moles of Cl per mole of CCl₂F₂ = 77 moles of Cl.

Thus, there are 77 moles of chlorine in 38.5 moles of dichlorodifluoromethane.

Answer:

77 moles

Explanation:

The given chemical compound is CCl2F2 is called Dichlorodifluoromethane. In CCl2F2, we have:

one mole of a Carbon atom.

two moles of Chlorine atom; &

two moles of Fluorine atom.

Given that one mole of Chlorine = 38.5 moles.

Then, two moles will be:

= 2 × 38.5 moles

= 77 moles
