A student determines the iron(III) content of a solution by first precipitating it as iron(III) hydroxide, and then decomposing the hydroxide to iron(III) oxide by heating. How many grams of iron(III) oxide should the student obtain if his solution contains 56.0mL of 0.586M iron(III) nitrate? Use the References to access important values if needed for this question.
