What is the mass percent of silver in silver chloride (AgCl)?

• A. 75.3%
• B. 63.5%
• C. 87.2%
• D. 52.9%

Answer: (A)

Verified step by step guidance

1. Identify the chemical formula of silver chloride, which is AgCl, consisting of one silver (Ag) atom and one chlorine (Cl) atom.
2. Find the atomic masses of silver and chlorine from the periodic table: silver (Ag) has an atomic mass of approximately 107.9 g/mol, and chlorine (Cl) has an atomic mass of approximately 35.5 g/mol.
3. Calculate the molar mass of silver chloride by adding the atomic masses of silver and chlorine: \(M_{AgCl} = M_{Ag} + M_{Cl}\).
4. Determine the mass percent of silver in silver chloride using the formula: \(\text{Mass \% of Ag} = \left( \frac{M_{Ag}}{M_{AgCl}} \right) \times 100\%\).
5. Substitute the values into the formula and simplify to find the mass percent of silver in silver chloride.
