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
