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?
