Answer to Question #243897 in General Chemistry for Phiwa

Question

In an electroplating cell. 0.485 g of a metal Mare plated out from an acidic solution of MO, in exactly
ne hour using a current of 1.50 A What is the molar mass of M?
Raduction equation
- M

Answer 1

$Q= it$

Q=1.5×60×60= 5400c

If 0.485g is electroplated by 5400c, then 96500c can electroplated;

(96500/5400)×0.485

Molar mass=8.67g
