Answer #1

Given data:

The power capacity of the battery is then

When the battery is discharged to 80%, the charge transferred from the battery is

This means the number of electrons transferred in the discharge reaction is

The amount of PbSO4 formed can be calculated from the number of electrons transferred. From the discharging chemistry, two electrons are transferred from the negative plate to the positive plate to form 2 PbSO4. The molecular mass of PbSO4 is

Thus, the amount of PbSO4 formed is

The total mass of the battery is 40 lb. Thus, the amount of PbSO4 formed is roughly 2% of the total mass of the battery.
