This chapter I have study during my last semester. It very enjoyful of study. First of all, I have been to introduce to syllabus of study such as Units and Dimensions, Conversion of Units and lastly about System of Units.
Although I have study this kind of subjects, I have mets some difficulities in converting units like calculating average molecular weight of a compound. However,I'm now getting more understanding about converting a units by doing a lot of exercise and practice.
