Assuming a total pressure of 0.967 atm , what is the partial pressure in atmospheres of H2O in the air?

Because a model would make the investigation easier to understand

Idk the answer sorry

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck

Remember that rust prevented by placing a sacrificial electrode in electrical contact with the iron. the sacrificial electrode must be composed of a metal that  oxidizes  more easily than iron (that is, it must be below iron in table 18.1).
