When 1.597 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 5.013 grams of CO2 and 2.052 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 28.05g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon. Enter the elements in the order presented in the question. empirical formula = molecular formula = According to the following reaction, how many moles of carbon dioxide will be formed upon the complete reaction of 29.2 grams of butane ( C4H10 ) with excess oxygen gas? butane (C4H10)(g)+ oxygen (g) Carbon dioxide (g)+ water (g) moles carbon dioxide
