3. suppose a student determined the empirical formula of the compound to be k3[fe(c2o4)3] 2h2o, rather than the correct formula that has three waters of hydration. propose an experimental error that might account for this incorrect formula (math/calculation errors are not acceptable answers).

Explanation:

When determining empirical formulas of hydrates we have to find the mass of water which left the hydrate when heating The sample. This amount of water calculated will provide us with the correct ratio of moles water / moles anhydrate since moles water > moles anhydrate. The mistake might have been done while determining the water that left the sample so then we see and impropre result in ratios.
