n-Butyl phthalate is used as an insect repellant and is composed of carbon, hydrogen and oxygen. When a 0.3413 g sample was subjected to combustion analysis, 0.2430 g of water and 0.8633 g of carbon dioxide is produced. In another analysis, the molecular weight was determeined to be 278.38 g/mol Calculate the empirical forumla and molecular formula Also provide some important highlights, which was discussed in class, on how you solve this problem. If stoichiometry is involved be sure to draw the stoichiometry maps associated with the problem
