Treatment of a 10.00\text{ g} sample containing a chloride salt with excess silver nitrate solution produced 8.08\text{ g} of silver chloride. (\text{Ag} = 108, \text{Cl} = 35.5)
Which of the following expressions can be used to calculate the percentage of chloride in the sample?
- (A)
\frac{143.5 \times 8.08}{35.5 \times 10.00} \times 100 - (B)
\frac{35.5 \times 8.08}{143.5 \times 10.00} \times 100 - (C)
\frac{35.5 \times 10.00}{143.5 \times 8.08} \times 100 - (D)
\frac{143.5 \times 10.00}{35.5 \times 8.08} \times 100
