When you're trying to find the percent yield in stoichiometry, it's super important to avoid common mistakes. This can help you save time and get better results. Here are some things to watch out for:

1. Don’t Mix Up Actual Yield and Theoretical Yield:

   • Actual yield is what you actually get from your experiment.
   • Theoretical yield is what you expect to get based on calculations.
   • Mixing these up will mess up your results!

2. Set Up Your Calculations Correctly:

   • Make sure your formula for percent yield is right.

   • It should look like this:

     $\text{Percent Yield} = \left(\frac{\text{Actual Yield}}{\text{Theoretical Yield}}\right) \times 100$

   • A common mistake is swapping these two values by accident.

3. Pay Attention to Significant Figures:

   • When you write your final answer, you need to look at significant figures based on your data.
   • For example, if your actual yield is 8.0 grams and the theoretical yield is 10 grams, your answer should reflect the least precise measurement.

4. Handle Units Carefully:

   • Always check your units.
   • If you're working with grams, make sure all the parts of your calculation are also in grams to keep things consistent.

By being aware of these common mistakes, you will get better at doing stoichiometric calculations!
