These questions require more thought and integrate several concepts.

Fluorine, F₂, is made by the electrolysis of anhydrous HF.

Typical electrolysis cells operate at 4000 to 6000 A and 8 to 12 V. A large-scale plant can produce about 9.0 metric tons of F₂ gas per day.

(a) What mass in grams of HF is consumed?

(b) Using the conversion factor of 3.60 × 10⁶ J/kWh, how much energy in kilowatt-hours is consumed by a cell operating at 6.0 × 10³ A at 12 V for 24 h?
