How does impurities affect percent yield?
Well, because they are present, they will lead to an overestimation of actual yield.
Water is without a doubt the most prevalent impurity in isolated laboratory products. Water clings to samples, making them difficult to dry, and its presence will inevitably increase product mass and significantly lower melting points.

Impurities affect percent yield primarily by artificially inflating the mass of the product, leading to a higher calculated percent yield than the actual yield of the desired product. In chemical reactions, if the reactants contain impurities, these impurities may not react, and thus they become part of the final product mass without contributing to the desired product. This can make it seem like more product was produced than was actually the case. On the other hand, impurities in the reactants can also lower the percent yield if they react with the reactants or catalysts to form undesired products, effectively competing with the desired reaction pathway and reducing the amount of desired product formed. In summary, impurities can both increase the apparent percent yield by contributing additional mass to the product and decrease the actual yield of the desired product by interfering with the reaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
