I have a question and I've shortened it down to: If all the carbon in a sample was converted to give 1.69g of CO2. Whats the percentage of carbon in carbon dioxide?
I'm really stuck and i don't know how to work it out. Please help.

you can find mole of CO2 : mass of CO2/Mr of CO2(44) = 1.69/44 1 mol CO2 has 1 mol C, so mol of C and CO2 are the same. Mass of C = nxM = (1.69/44)x12 how percentage of C ? so easier when you know the mass of sample and C %mC = (mC x100%) / mass of sample But we don't know the mass of sample ??? Maybe the task is shorten ^^
