Nick** Many people in today’s world are finding that companies are not advertising the correct amount of nutrients in their products. The purpose of this experiment was to measure the amount of iron in a vitamin tablet. A colorimeter was used to measure the absorbance of particular wavelengths of light by the different solutions. In this experiment, 7.83 mg of iron was calculated by using the colorimeter and calculations (10% error from the 9 mg of iron labeled on the nutrition facts). This data shows that the vitamin tablet did have the correct amount of iron in it.
