However with practice, the accuracy could be improved; accuracy being how close the results are to the real answer. I think I have carried pit the experiment as well as I possibly could at the time with the given conditions and time period allowed. I have gained precise results from the practical. However, looking back at the analysis section, the relative atomic mass values I found were not exactly 6.9 as presented in the periodic timetable. Method (1) gave me 8.28; a difference of 1.38 and method (2) gave me 7.37, a difference of 0.43 to the real/reference value. Therefore method (2) proved to be more accurate.
