Zinc plating (galvanizing) is an important means of corro-
sion protection. Although the process is done customarily by dip-
ping the object into molten zinc, the metal can also be electroplated
from aqueous solutions. How many grams of zinc can be depos-
ited on a steel tank from a ZnSO4 solution when a 0.855-A current
flows for 2.50 days?
