(chemistry only) Use an appropriate number of significant figures in percentage-yield answers. (MS 2a)

In chemistry, when calculating percentage yield, it is essential to use an appropriate number of significant figures in your answers. Significant figures reflect the precision of your measurements and calculations. For instance, if the actual yield of a product is 12.3 grams and the theoretical yield is 15 grams, the percentage yield should be calculated as (12.3 / 15) x 100, which equals 82%. Here, the answer should be reported with three significant figures, consistent with the least precise measurement. This practice ensures clarity and accuracy in scientific communication.
