Question

Deshawn carefully mixes the substances together in an Erlenmeyer flask. When mixed together, the substances undergo a change. Afterward, Mimi measures the mass and finds it to be 10 grams. Mimi and Deshawn repeat this experiment twice more with the same results. What is the most likely explanation for this data?

Answer 1

The consistent mass measurement of 10 grams in the experiments conducted by Mimi and Deshawn supports the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction.

Step-by-step explanation:

The most likely explanation for the data showing that the mass of the mixture in the Erlenmeyer flask is 10 grams after each experiment is the law of conservation of mass. This law states that mass is neither created nor destroyed in a chemical reaction.

In the given experiments, even though the substances undergo a change, their total mass remains constant. The observations that Mimi and Deshawn made align with this principle, similar to how a quality control chemist ensures the accuracy and precision of measuring instruments in a pharmaceutical company. Just like the consistent volume of cough syrup dispensed by the machines, the repeated mass measurement of 10 grams underscores the repeatability and reliability of the chemical process in question.
