For each piece of glassware measure the density of water in triplicate (three times). Why repeat the procedure multiple times for each piece of glassware? Running the measurement in triplicate increases the precision of our results and reduces the impact of a single outlier result. The experiment would be too short if you only ran each trial once The first two trials act as practice, and the final trial will give you the true result. Running the measurement in triplicate increases the accuracy of our results and reduces the impact of a single outlier result

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
