Calculate the mass of silver chloride required to plate 195 mg of pure silver.

Given information:

Mass of pure silver = 195 mg

To determine:

Mass of silver chloride required to plate 195 mg of pure silver

Calculation:

The silver chloride used for silver plating usually contains 75.27 % silver

i. e.

every 100 mg of silver chloride will contain 75.27 mg silver

therefore, amount of silver chloride corresponding to 195 mg of silver would be = 195 mg * 100 mg/75.27 mg

= 259.1 mg
