Question

0.222g of a divalent metal is deposited when a current of 0.45ampere is passed through a solution of salt for 25min. Calculate the relative atomic mass of the metal

Answer 1

numberatoms=charge/(2*1.6e-19)= 2.109375e21

moles metal= numberatoms/avagnumber= 2.1e21/6.02e23=.0035
relative atomic mass=.222/.0035=63.4 grams
