Question 7

Galvanising is a method of rust prevention where iron is coated with a protective layer of zinc.

An industrial steel I-beam used in construction has a total surface area of 8.4 m2. To protect it from atmospheric corrosion, the beam is to be galvanised.

Calculate the mass of zinc, in kilograms (kg\text{kg}kg), required to coat the surface of this beam with a zinc layer of 450 g m-2.
