As stated in the background information, carbohydrates have the empirical formula ch20, while fats typically have an empirical formula of about c10h190. a. (1.5 pts) calculate the percent oxygen by mass in each of these biomolecules using the atomic masses of the elements on the periodic table. show the math, units, and correct significant figures. och2o = 16.00 amu 12.jamu +(2x1.008amu) + 16.00 am x100% 353-29% 16.00 am clox 12.01 amu) +c19x1.008 amu) +16.00 ama x 100% 10.31% b. (1.5 pts) which of these biomolecules will release more energy when metabolized in the body and why? compare three different snack foods and cite the data. fat will release more energy
