I'm doing some past papers to prepare for my upcoming science assessments and there's this one chemistry question that I got wrong, but the mark scheme just gives the answer and doesn't show how you get there? I can't find anything so if someone could help that would be great lol
An iron ore contains 22% by mass of iron(III) oxide. Calculate the maximum mass of iron that could be obtained from 5 × 10^5 tonnes of this ore. Give your answer in standard form.
