`100mL` of a colloidal solution is completely precipitated by addition of `5mL` of `1M` `NaCl` solution. Calculate the coagulation value of `NaCl` .

Explanation

To calculate the coagulation value of NaCl, we will follow these steps:

### Step 1: Determine the number of moles of NaCl used
We know that:
- Molarity (M) = 1 M (for NaCl)
- Volume (V) = 5 mL = 5/1000 L = 0.005 L

Using the formula for moles:
...
