Could somebody explain how the whole ratios thing works? Also I don't understand how you figure out a symbol equation having only the worded question.
Do I have to convert everything into dm^3??
Also I can't find any questions to practise that have answers so I can check. I've tried bitesize but they dont really have q&a's.
Sorry about all the questions I just want to ensure I get the hang of this before Wednesday.
I'm doing AQA Triple if that's any use.
...or just paranoid?
