A copper plate of `10cmxx10cm` and `0.1`cm thickness is to be placted with silver. If the density of Ag is `10.8`g/cc, the number of electrons required for this process is

A copper plate of 20 cm x 10 cm is to be plated with silver of 1 mm thickness on both the sides. Number of moles of silver required for plating is (density of silver =10.8 g m /cc)____________

A copper plate of 20 cm x 10 cm is to be plated with silver of 1 mm thickness on both the sides. Number of moles of silver required for plating is (density of silver =10.8 g m /cc)____________

A copper plate of 20 cm xx 10 cm is to be plated with silver of 1 mm thickness. The number of silver atoms required for plating is (density of silver = 10.8 gram// cc)

A current of 4 A is passed through a solution of silver nitrate to coat a metal surface of 80 cm^(2) with 0.005 mm thick layers of silver. If the density of silver (molar mass: 108 g "mol"^(-1) )is 10.8 g cm^(-3) , the time for which the current is passed is about

Find the number coulombs needs to plate 10 cm xx 10 cm area to a 0.1 mm thickness of copper metal (density 8.94 g c c^(-1) ) using aqueous cupric sulphate (At wt. of Cu is 63.5).

A brass plate (5 cm xx 4 cm ) is to be plated on both sides with a coating of thickness 0.25 mm . Calculate the strength of current so that work may be completed in 5 h . Electrochemical equivalent of silver is 0.00112 g C^(-1) and density of silver = 10.5 g cm^(-3) ,
