Question

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

Answer 1

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
