Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

42.20 Titre (cm3) 4.30 17.70 16.60 16.60 17.60 16.30 Therefore‚ the average titre would be calculated as follows; all the titre measurements added together (not including the rough titre)‚ and divide this amount by the total number of titrations taken. In this case‚ I am only going to find the average titre of 3 of the results because to have successive measurements‚ the titrations have to be within 0.1 of each other‚ and in this case it was for only 3 of the results shown above. The average titre

TMA 01 – Question 1 Mean: The maximum value of a series of measurements (or numbers) divided by the number of those measurements. The definition of the ‘mean’‚ is an array of numbers added together and then divided by the amount of those numbers. The reason the first definition is incorrect is because it isn’t the maximum value of figures‚ it’s the total amount added together. Scientific notation: A notation that represents any number by expressing it as a simple power of ten‚ using a positive

Testing Lab Report Introduction Objective measurement is a scientific way to get a good understand about some basic properties of fabric. In this lab‚ FAST system can provide the accurate measurement to show compression‚ extension‚ bending and stability of fabric. The aim of this test is to predict how a fabric will perform when made up into a garment. For fabric manufactures‚finishers and garment manufacturers‚ they can use the results of this test as a basis to do fabric specification‚

excess liquids had been removed‚ they were placed on the scale one at a time. The mass was then recorded in a data table. These steps were repeated in ten minute intervals four more times‚ each time recording the mass in the data table. After all measurements were collected‚ the percent of mass change was calculated using the formula listed below: 100(Mass after Immersion-Initial Mass) Initial mass Results After the fifty minutes soaking in the solution‚ the egg placed in water gained mass
