C. i. burning 0.539 g sample forms 1.361 g carbon dioxide All C in 1.361 g CO 2 came from the sample. All H in 0.239 g H 2 O came from the sample.
Empirical formulas show the simplest ratio of number of moles.
Assume all percentages are mass percentages, unless otherwise stated. Divide all calculated mole values by lowest value. 2.135 g of cmpd burns to form 5.462 g of carbon dioxide. All carbon in the 5.462 g CO 2 comes from the original cmpd. 2.135 g of cmpd burns to form 2.234 g water.
