In the crystallisation of `71.75` grams of `AgCl`, in molten state `1 xx 10^(4)` mole of cadmium chloride is added to cause impurity defect. Calculate (a) the number of `Ag^+` ions present, (b) the number of Cd2+ ions present and (c) the number of lattice vacancy defects.

Explanation

To solve the problem, we will break it down into three parts as per the question: (a) calculating the number of Ag⁺ ions present, (b) calculating the number of Cd²⁺ ions present, and (c) calculating the number of lattice vacancy defects.

### Step-by-Step Solution:

**(a) Calculate the number of Ag⁺ ions present:**

1. **Calculate the number of moles of AgCl:**
