Calculate the percentage of Chloride present in the sample? ?

To calculate the percentage of Chloride present in the sample, you need to know the mass of Chloride in the sample and the total mass of the sample.

Once you have these values, you can use the following formula to calculate the percentage of Chloride:

Percentage of Chloride = (Mass of Chloride / Total mass of sample) x 100

For example, if the mass of Chloride in the sample is 5 grams and the total mass of the sample is 100 grams, the calculation would be:

Percentage of Chloride = (5 / 100) x 100 = 5%

Therefore, the percentage of Chloride present in the sample is 5%.

Step 1: Determine the mass of Chloride (Cl)

- Convert the mass of AgCl from grams to moles:
```
Moles of AgCl = 0.250 g / 143.32 g/mol = 0.001743 mol
```
- Since the molar ratio of Cl to AgCl is 1:1, the moles of Cl are equal to the moles of AgCl:
```
Moles of Cl = 0.001743 mol
```

Step 2: Calculate the mass of Chlorine (Cl2)

- Use the molar mass of Cl2:
```
Mass of Cl2 = 0.001743 mol - 70.906 g/mol = 0.1234 g
```

Step 3: Determine the original mass of the sample

- This information is not provided in the context, so assume it is given as "x" grams.

Step 4: Calculate the percentage of Chloride (Cl)

- Divide the mass of Cl2 by the mass of the sample and multiply by 100:
```
Percentage of Cl = (0.1234 g / x g) - 100
```

Without knowing the mass of the original sample, the percentage of Chloride cannot be calculated.
