![**Problem:**
What volume (in L) of 1.10 M FeCl₃ would be required to obtain 0.760 moles of Cl⁻ ions?
**Explanation:**
To solve this problem, we need to understand the dissociation of FeCl₃ in water. One mole of FeCl₃ dissociates into one mole of Fe³⁺ ions and three moles of Cl⁻ ions:
\[ \text{FeCl}_3 \rightarrow \text{Fe}^{3+} + 3\text{Cl}^- \]
Given the molarity of FeCl₃ solution is 1.10 M, this means there are 1.10 moles of FeCl₃ per liter of solution. Hence, 1 liter of 1.10 M FeCl₃ will produce:
\[ 1.10 \times 3 = 3.30 \text{ moles of Cl}^- \]
To find the volume that provides 0.760 moles of Cl⁻ ions, use the proportion:
\[ \text{Volume of solution} = \frac{0.760}{3.30} \text{ liters} \]
**Tools:**
The display includes a calculator interface with numbers and basic arithmetic operations for input.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6a85ba4d-6f5c-41bf-97e5-182adb23b838%2F14120d49-6785-4771-a151-cfd80c0bd9ac%2Fpqr0fg_processed.png&w=3840&q=75)
