Ideally‚ the percent yield should be 100%‚ as this means that you have recovered 100% of that material. A yield over 100% would mean that the substance still has some traces of another material that is adding additional mass. Ex. The iron filings having some sand particles leftover. A yield under 100% would mean that some of the substance was not recovered‚ it could have been lost (spilled) or found in another substance (not separated completely). The percent yields may give some insight into what
