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

TECH0701: Measuring the Melting Points of Compounds and Mixtures Introduction This exercise dealt with the melting points of pure mandelic acid and benzoic acid. The eutectic temperature and composition of mandelic and benzoic acid mixtures were determined. And finally‚ an unknown was identified by its mixtures and melting point. The melting point of a compound is used by organic chemists not only to identify the compound‚ but also to establish its purity. To determine the melting point two

Hydrated Crystalline Compound Katie Sanders Science Block 3 February 29‚ 2012 Title: Analysis of a Hydrated Crystalline Compound Purpose: The purpose of our experiment was to determine the amount of water in copper sulfate pentahydrate expressed as a percent. Hypothesis: I think that bluestone crystals are 20% water‚ because it’s called pentahydrate (penta means five) and 1/5 of 100 (since it’s expressed as a percent) is 20‚ so I think

Orwell wrote this allegorical novella in England when the wartime alliance with the Soviet Union was at its height and Stalin was held in highest esteem in Britain both among the people and government.
