A 0.1592g sample of a hydrocarbon upon combustion analysis produces 0.5008g CO2. Its molar mass is found in another experiment to be 70g mol. Determine the empirical formula, and its molecular formula.
I completely messed up this question, and I don't know where I wen't wrong. My empirical formula: CH. The correct answer: CH2. Can someone help me how to get the right answer?

Oh sorry, the question also gives this information:the 0.2041g of H2O were also produced.
Sarah, why don't you show your work and let us find where you went wrong (instead of us working everything including what you did right and letting you check to see where we went right).
I figured out I went wrong when calculating the moles of hydrogen. I used the molar mass of just one hydrogen since I was calculating the moles of one mole of hydrogen. I didn't know that I had to 2X the g/mol of hydrogen. Is there an explanation why this is?
