Question

sove it explanation if u can....

Answer 1

Ag - + e-      ----> Ag

R.A.M. of Ag = 107.87

One mole of silver ions (107.87g)  require one mole of electrons.
∴ 0.7 g = 0.7/107.87 moles of electrons
             = 0.00645 moles of electrons


1 mole of electrons ≡ 96500 Coulombs
∴ 0.00645 moles of electrons ≡ 0.00645 x 96500
                                                    = 622.425 Coulombs
