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.
Calculate the empirical formula of a compound that only contains C, H, O, and F. A 7.03 g sample has undergone combustion and produced 13.0 g CO 2 and 4.26 g H 2 O. A second sample of the compound that weighs 6.13 g is found to contain 0.98 g F.
Several of the problems below include this question and you can go here for a discussion about calculating the molecular formula once you know the empirical formula. Example #1: A 1.50 g sample of hydrocarbon undergoes complete combustion to produce 4.40 g of CO 2 and 2.70 g of H 2 O.

Combustion Analysis Problem Answers for Problems 1, 2, and 3. 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. Solution: Carbon: (1.321 g) (12.011 / 44.0098) = 0.3605 g
12 Φεβ 2023 · Determine the empirical formula of a compound using combustion analysis. When a compound containing carbon and hydrogen is subject to combustion with oxygen in a special combustion apparatus all the carbon is converted to CO 2 and the hydrogen to H 2 O (Figure \(\PageIndex{1}\)).
