The Alpha-linolenic acid is one of a large group of fatty acids that are found in fish oil, walnuts and canola seeds. These nutrients are necessary for good health. All of these fatty acids contains of an unsaturated hydrocarbon that is terminated by a carboxylic acid functional group. When a 12.47554 g example of unknown fatty acid is burned in oxygen, the process consumes 30.24 g of O2. Explain the reaction produces 33.8877 g of CO2 and 8.82784 g of H2O. Based on these results as well as the molar masses of H (1.008 g), C (12.01 g) and O (16.00 g), how many hydrogen atoms are in each formula unit of the acid, CxHyO2? (What is the value of y?)
