actually this doesn't have any proper formula...in the chemistry 'revision guide' also it is mentioned that it is better to draw the molecular formula rather than using a formula...

OR another solution, as mentioned by wooowooowoo that learn it for methane, and for others 'subtract' one 'carbon' atom...for instance...if it is butane...you will take the n as 3 NOT 4...hope you get what i am trying to say?

Thank youuu :D I'll have to do it the long way then :)

anyone do the physics practical 52? so freaking lengthy and our school is just stupid. my glass slab was not shaped exactly like a rectangle it was tilting at one edge so i got my refractive indexes different and they didnt even setup the force experiment at the start. im sure no one loses more than 5 marks in these practicals but i know im gonna lose atleast 10 :(

How did you do in paper 1/3?
Shouldn't worry too much, 10 marks in paper 5 ( if it's out of 40) is only 5% of total grade, and last year p3 was easier than this but grade threshold was 70-75%(EDIT: For an A* that is) so don't worry!
