Question

Calculate the maximum mass of iron that can be obtained from 240 tonnes of iron oxide

Answer 1

Answer:

167.86 tonnes

Explanation:.

I am assuming the iron oxide is Fe2O3 (Haematite) which is the most common form of iron oxide.

From the atomic masses:

Maximum Mass of iron = 240 *  2*55.845 / (2*55.845 + 3*15.999))

= 240 * 111.69 / (159.687)

= 167.86 tonnes
