How many grams of silver could be plated out on a serving tray be electrolysis of solution containing silver in `+1` oxidation state for a period of `8.0` hour at a current of `8.46` ampere? What is the area of the tray if the thickness of the silver plating is `0.00254 cm`? Density of silver is `10.5 g//cm^(3)`.

Answer

`1.02xx10^(4)cm^(2)`

Explanation

Calculate mass of Ag deposited. It comes out to be 271.65 g. volume of Ag deposited `=(271.65)/(10.5)=25.9cm^(3)`
area of tray`=(25.9)/(0.00254)=1.02xx10^(4)cm^(2)`.
