    Write down the equation in terms of the variables.



    From studying this equation, we see that:



    Find the relative molecular mass of CO2 and that of H2O. Find the number of moles of each that was produced to get the value of x and y. From there, try to balance your equation to get the value of z.

    When you're done with that, you will have the molecular formula of the sample. The empirical formula should be easy now. :)
