Combustion analysis and empirical formula calculations. Compound A contains 55.17% carbon, 8.05% hydrogen and the remaining percentage by mass is oxygen. Calculate the empirical formula for compound A and, given that 0.025 mol of the compound weighs 4.35 g, determine the molecular formula.
Problem #1: 0.487 grams of quinine (molar mass = 324 g/mol) is combusted and found to produce 1.321 g CO 2, 0.325 g H 2 O and 0.0421 g nitrogen. Determine the empirical and molecular formulas. Problem #2: 95.6 mg of menthol (molar mass = 156 g/mol) are burned in oxygen gas to give 269 mg CO 2 and 110 mg H 2 O.
Combustion Analysis Practice Problems. 1.) Researchers used a combustion method to analyze a compound used as an antiknock additive in gasoline. A 9.394 mg sample of the compound yielded 31.154 mg of carbon dioxide and 7.977 mg of water in the combustion. Calculate the percent composition of the compound.
Combustion Analysis gives % composition • Compounds containing C, H and O are routinely analyzed through combustion in a chamber like this – %C is determined from the mass of CO 2 produced – %H is determined from the mass of H 2O produced – %O is determined by difference after the C and H have been determined C nH nO n + O 2 nCO 2 + 1/2nH
Scientists have many techniques to help them determine the chemical formula or structure of an unknown compound. One commonly used technique when working with carbon-containing compounds is combus-tion analysis. Any compound containing carbon and hydrogen will burn.
Combustion Analysis Extra Problems Key. Combustion Analysis Problems (optional): Key. A hydrocarbon fuel is fully combusted with 18.214 g of oxygen to yield 23.118 g of carbon dioxide and 4.729 g of water. Find the empirical formula for the hydrocarbon.
