I got the question correct by following your working THANKS
In order for a titration to be rough it must be o.2 cm^3 away from the other ? In the 2015 paper it doesn't say rough titration it just says titration 1,2,3.
Oh and if the number of moles isn't 1 what numbers would I put in the equation ?

I would just use the 2nd and 3rd one to be on the safe side. Where it says n1 or n2, put in the number of moles e.g if it was 2c6H12O6, the is 2 where the n would be instead of one.

how many marks are balancing equations worth and are they really important to know. Also what are the best things to learn if you are looking to scrape a pass would really appreciate it if someone answered thanks

You may get a multiple choice question on balancing equations, or there may even be a question on it in section 2, You also need to know how to balance equations as part of a calculation.
If you want an easy 3 marks look at how to calculate the rate of reaction Unit 1
Just a quick question... In titration questions the Volumes are in cm^3 I change it to litres when doing the question but do I change it back when I have an answer ?

1 mark usually.
Learn Eh=Cm DeltaT - This is worth 3 marks Learn =change in quanitity/change in time - Easy 3 marks Mole calculations, So n=cv n=mass/gfm - Easy few marks

@Aston177 Also learn percentage Mass calculations, another easy 3 marks
Thanks so much for the help so far guys. I would like to ask when you are told to work out the gfm but are given the solution in words how do you find that out?
