Alevel Chemistry harder amount of substance questions

I am really struggling with amount of substance questions, and back titration questions on AS physical Chemistry. Can anyone offer any advice also I am unsure which moles to compare like for some questions they compare the molecule with the least amount of moles on the LHS to the RHS whereas in some questions they compare the Moles of the molecule with the most moles on the LHS to RHS.
