Question

1. In electroplating a silver spoon,how many moles of electrons are required to deposit 10.8g of silver (Ag=108)

Answer 1

0.1 moles of electrons

Step-by-step explanation:

Electroplating is a process in which a metal is used to cover the surface of another metal for protection or beautification purposes.

The reduction of the silver is captured in the equation;

Ag^+(aq) +e ------> Ag(s)

We were already told in the question that the mass of silver is 108g

1 mole of electrons is needed to deposit 108g of silver

x moles of electrons is required to deposit 10.8 g of silver

x= 1 ×10.8/108

x= 0.1 moles of electrons
