A saturated solution of AgCl at 25°C contains \([Ag^+] = 1.3 \times 10^{-5}\,\text{M}\). The solubility product of AgCl increases by 20% when the temperature is raised to 35°C. Assuming no common ion is present, calculate (a) the solubility of AgCl at 35°C in mol\,L\(^{-1}\), and (b) the mass of AgCl that can dissolve in 250\,mL of water at this temperature. Give your answers in scientific notation with three significant figures.

Answer Options

A. Solubility = 1.55×10⁻⁵ M; mass = 5.60×10⁻⁴ g
B. Solubility = 1.20×10⁻⁵ M; mass = 4.30×10⁻⁴ g
Correct Answer C. Solubility = 1.42×10⁻⁵ M; mass = 5.10×10⁻⁴ g
D. Solubility = 1.42×10⁻⁵ M; mass = 4.80×10⁻⁴ g
Correct Answer
C
Correct Option:
Solubility = 1.42×10⁻⁵ M; mass = 5.10×10⁻⁴ g
