Complete combustion of a sample of propane produced 2.641g of carbon dioxide and 1.442g of water as the only products. Find the empirical formula of propane.

I have already calculated the number of moles for both water and carbon dioxide. I also know that propane is only carbon and hydrogen, but I am not exactly sure where to go from here.

  • Chemistry -

    Convert moles CO2 to moles carbon.
    Convert moles H2O to moles hydrogen.
    Then determine the ratio of the two elements to each other. The easiest way to do that is to divide the smaller number by itself (thereby obtaining 1.000 for that element); then divide the other number by the same small number. Round to whole numbers if close to a whole number or multiply both by a factor if one of the number is 1/2
    Post your work if you get stuck.

    Now say when your converting CO2 to moles carbon, do you multiply by (1 mole C/1 mole CO2)?
