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

the other which is the pool fish. Each group of student picked out 8 fishes each and measured it with a ruler. For the length‚ it was measured from mouth to where the tail stared‚ and for the depth‚ the measurement was done from fin to fin without pulling the fins as not to get a wrong measurement. Once the raw data was collected‚ the ratio of depth and length was calculated to get the proportional difference in the fishes rather than getting their height. Soon as

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
