A1.367g sample of an unknown organic compound is combusted with oxygen to give only 1.459 g H2o and 3.055 g of Co2. What is the empirical formula of the compound?

  • Chemistry -

    Does the compound contain ONLY C and H? If so, then convert grams CO2 to moles C and convert grams H2O to moles H (H and not H2).
    Then find the ratio of C and H to each other with the smallest number being 1.00.
    Frankly, I think you have made an error in posting because if I add g carbon and g hydrogen, I don't end up with 1.367g unknown. So the extra mass could be due to oxygen, nitrogen, sulfur, or some other element. Check your post.
