Determining an empirical formula using combustion analysis - Crunch Chemistry

SOLVED: A combustion analysis is a technique to find the empirical formula of compounds. In a combustion analysis experiment, 0.8657 g of an organic compound containing only carbon, hydrogen, and oxygen is burned in oxygen, forming 11.190 g of CO2 and 10.3248 g of H2O. What is the empirical formula of the compound?Write the numbers that you would write in the subscript of the formula in the boxes next to the symbol of the element.C()H()O()
