I really don't understand this chemistry calculation. Can anyone help??
A sample of 3.230g of unsaturated chloroflurocarbon (a compund containing carbon, fluorine and chlorine only) was analysed as follows:
All the carbon in the sample was converted into carbon dioxide gas, which was then bubbled through excess limewater. Highly insoluble calcium carbonate weighing 4.864g was produced.
A further sample of the chlorofluorocarbon weighing 3.230g was vapourised in the absence of air and produced 545mL of vapour at STP.
A third sample of the compound was analysed and was found to contain 28.6% by mass fluorine.
(a) Determine the empirical formula of the compound.
(b) Determine the molecular formula of the compound.
(c) Draw two possible structures of the compound.
I don't even know where to start on this question, and i've wasted so much time looking around on the internet. Any help on how to do this would be great. (working out is crucial, otherwise I a won't learn a thing). Thanks.
