Question

If 0.22grams of a divalent metal is deposited when a current of 0.45ampere is passed through a solution of a salt for 25 minutes. Using appropriate electrodes, calculate the relative atomic mass of the metal. (Faraday=96500)

Answer 1

How many Coulombs do you have? That's
C = A x seconds = 0.45 x 25 min x 60 s/min = about 675
96,500 C will deposit M/2 g of the metal where M is the atomic mass.
So M/2 x 675/96,500 = 0.22
M = ? = atomic mass of the element.

Answer 2

0.222g of a divalent metal is deposited when a current of 0.45 ampere is passed through a solution of its sought of 25mins.calculate the relative atomic mass of its metal

Answer 3

yes
