A current of 5A was passed through a solution of nickel (1)(1))salt.find the time taken for 6g of nickel to be deposited

Answer 1

Oh my. How many electrons?

Nickel is 58.7 grams per mole or 6*10^23 atoms which here is 6*10^23 electros
so
6 g * 6.022*10^23 electrons/58.7 g
= .6155 * 10^23 electrons

1.602*10^-19 coulomb/electron

so the product is
.986 * 10^4 Coulombs

a coulomb is an amp second
so
.986*10^4 = 5 t

t = .197 * 10^4 seconds

= 1970 seconds
= about 33 minutes
check my algebra !
