The correct Answer is:
To solve the problem, we need to determine how many moles of AgCl will be precipitated when excess AgNO₃ is added to a solution of dichlorobis(ethylenediamine)cobalt(III) chloride. ### Step-by-Step Solution: 1. **Identify the given data**: - Volume of the dichlorobis(ethylenediamine)cobalt(III) chloride solution = 100 mL = 0.1 L - Molarity of the solution = 0.024 M 2. **Calculate the number of moles of dichlorobis(ethylenediamine)cobalt(III) chloride**: - Use the formula: \[ n = \text{Molarity} \times \text{Volume} \] - Substitute the values: \[ n = 0.024 \, \text{mol/L} \times 0.1 \, \text{L} = 0.0024 \, \text{moles} \] 3. **Determine the number of chloride ions**: - The formula for dichlorobis(ethylenediamine)cobalt(III) chloride indicates that there are 2 chloride ions per molecule. Therefore, the number of moles of chloride ions is: \[ \text{Moles of Cl}^- = 2 \times 0.0024 = 0.0048 \, \text{moles} \] 4. **Reaction with AgNO₃**: - When excess AgNO₃ is added, it will react with the chloride ions to form AgCl. The reaction is: \[ \text{Cl}^- + \text{Ag}^+ \rightarrow \text{AgCl} \] - Since we have 0.0048 moles of chloride ions, this means that 0.0048 moles of AgCl will be precipitated. 5. **Conclusion**: - The total moles of AgCl precipitated will be **0.0048 moles**. ### Final Answer: 0.0048 moles of AgCl will be precipitated.
