Combustion analysis of 0.300 g of an unknown compound containing carbon, hydrogen, and oxygen produced 0.5213 g of CO2 and 0.2835 g of H2O. What is the empirical formula of the compound?


  • Chemistry -

    Convert g CO2 to percent C.
    Convert g H2O to percent H.
    Add %C and %H and subtract the sum from 100 to obtain %O.

    Then take 100 g sample which will give you the percents in grams.
    Convert gC, gH, and gO to moles. Then find the ratio of each element to the smallest in whole numbers.
    Post your work if you get stuck.
