I got some calculations i am having trouble with to do with moles and concentrations etc..
Does any1 have any example questions (simple ones) to get me on the right track.
I just need to know how important it is to know how to do all the calculations from year 11 with moles..etc going on into year 12. Does yr12 chem involve alot of calculations and 'maths' or is it just about knowing facts?
