Post-lab Questions
1. What is the empirical formula for the iron oxide in this experiment? Show all work at the end of the worksheet.
Click or tap here to enter text.
2. Does your empirical formula agree with the expected empirical formula? The expected form of iron oxide in rust
is iron(III) oxide.
The expected empirical formula of Iron (III) Oxide is Fe203. So, my empirical formula is different
because it has the same amount of O and Fe and in the expected formula there is more O than Fe.
3. Briefly explain why your results may not match with the expected empirical formula, and propose how the
experiment could be modified to give better results.
