    Description Whenever we do experiments‚ the actual result is a little different from the result we predicted. In chemistry‚ this discrepancy is compared by calculating the percent yield. In this lesson‚ we will define percent yield‚ and go over a few examples. !!!What is Percent Yield? Sometimes you look at a recipe and it says how many servings it will make if you follow the amounts listed on there. There are times‚ however‚ that the number of servings after you have made the food is not the

    In contrast‚ a measure of precision can be made using the results. Precision refers to how close a set of results are to each other. In this lab‚ the percent relative average deviation can be used as an indicator of preciseness. Percent relative average deviation is a measure of how tightly clustered a set of data points is around a mean. A low percent relative average deviation indicates that the data points are tightly clustered around the mean; moreover‚ if the
