If 10 C of electricity is passed through an aqueous solution of a metal salt , `2.08xx10^(19)` atoms are produced at the cathode . Find the equivalent weight of the metal , if its atomic weight is 27 .

Text Solution

Verified by Experts

`2.08xx10^(19)" atoms "=(2.08xx10^(19))/(6.023xx10^(23))=3.45xx10^(-5)" mol."`
`10C-=3.45xx10^(-5)" mol atoms"`
`therefore" "96500C-="0.333 mol "-=0.333xx27-=8.98`.
`therefore" Equivalent mass of the metal = 8.99."`
