(Atomic mass of zinc = 65.4 amu)

Canvas Classes · Accepted Answer

Strategy:
 Apply Faraday's Law  to calculate the mass of Zinc deposited by a steady current. Ensure time is in seconds.

Step 1: Calculate total charge passed ()
, .

Step 2: Apply Faraday's law for mass
Zinc ion is , so .
Equivalent weight of Zn .

Step 3: Format the result
.
