hi guys, does anyone have worksheets or notes relating to Chapter 3, F4 ( stoichiometry )
or any worksheets on all chem calculations
Hi krieti, you should definitely refer to Youtube, there are some impressive videos from tutors that provide guidance on Stoichiometry. They too provide sample questions to try out too.
here is one that really helped me out. Good Luck. 
This is amazing as I found it very much useful and informative to be honest.
