Paper 53 Nov2011 chemistry answer discussion!!!!

then based on ur experience..ll we get the ecf mark for that ? for the error that we had made..just deduct 1 mark for wrong calculated mole of oxygen...coz the answer no matter wat we divided..either 16 or 32 are the same...so i think they ll just deduct 1 mark for the mistake and other parts...
